1 – 1 Identifying and Counting Numbers to 100
It is very important that you know how to count numbers. It is also important that you
can identify the numbers and say their values. You have worked hard on learning your
numbers from 1 through 20. Let’s count these numbers together. Please count along
with me. So here we go,

Nice work! Now we are going to learn the numbers that come after 20 all the way up to
100. There are a few patterns I am going to show you that will make counting to 100
easier.
Let’s look at the next few numbers after 20 and you tell me when you see a pattern.
The number after 20 is 21, then the next number is 22 and the next is 23.
21
22
23

twenty-two
twenty-three
Do you see the pattern? What number do you think comes next? Yes, 24! To come
up with all the numbers in the 20s, you just put the numbers 1 through 9 after the 2.
Try counting from 21 to 29 with me.

Very good! Now we need to figure out the next number after 29. Well, the next
number after 9 is 10, so let’s change the number 9 to a 0 and add the 1 to the 2, which
makes the number 3. So, the number 29 becomes 30.
Now, the 30s follow the same pattern that the 20s followed. Do you remember that
pattern?
If you said to put the numbers 1 through 9 after the 3, great job! Now, let’s count the
numbers 30 through 39 together.

Very good! You are really great at counting! Now we need to figure out the next
number after 39. So, just like we did before, the number 10 comes after 9, so change
the 9 to a 0 and add that 1 to the 3, which will make 40. So, what is the next number
after 39? Yes, 40!
Now, I can tell you that the 40s also follow the same pattern as the 20s and 30s, can
you tell me that pattern? If you said to put the numbers 1 through 9 after the 4, then
you are really getting the hang of this! Now, let’s count the numbers 40 through 49
together.

Great job! Now it’s time to show you the second pattern that makes counting to 100
easier. So far we have counted to 20, then we counted all the numbers in the 30s and
40s. Do you see a pattern in just these three numbers: 20, 30, 40?
Yes, the first number (also known as the ten’s place) counts by 1. So, it goes 20, 30,
40, 50, 60, 70, 80, 90 and finally 100. All the numbers in between repeat the first
pattern I showed you, which is where the second number (also known as the one’s
place) repeats the numbers 1 through 9 before letting the first number move up one.
Let’s review all the numbers to 49 again. The numbers are shown here.

Now, the next number after 99 can be tricky. Do you know this number?
There is no tricking you! Yes, the next number is 100. Why? Remember how I
explained earlier that the next number after 9 is 10, so we change the second number
(the one’s place) to a 0 and added the 1 to the first number (the ten’s place). In this
case the first number is 9 too, so 9 turns to 10. 10 and 0 makes 100.

Congratulations! You know how to count to 100 now!

1 – 2 Identifying and Counting Numbers Past 100
Great job learning how to count to 100! Did you know that numbers go way higher
than 100? They do. Now we are going to learn all the numbers from 101 to 1,000.
We just use the same patterns when counting to 100, just with bigger numbers now.
Please count along with me. So here we go,

Great job! See how the numbers 101 through 120 are similar to the numbers 1 through
20? The difference with the bigger numbers is that you say “one hundred” in front of
the numbers 1 through 20.
Now we use the same pattern we used when counting from 20 to 29, except we still
have the “one hundred” in front of the number. Let me show you what I mean. I am
going to count and if you can, please count with me.

Did you see the pattern? After the words “one hundred twenty” we used the
numbers 1 through 9 one at a time. This pattern keeps repeating all the way to 1,000.
Try counting to 200 with me.

Great job! Can you guess what number comes after 199? If you said 200, you are
right! The next number after 9 in the one’s place is 10, so we change the number 9 to
a 0 and add the 1 to the 19, which makes the number 20. So, the number 199
becomes 200.
The same patterns we learned when counting to 100 is used when counting even
higher too.
So, if we were to skip all the numbers in between and just count the hundreds, we
would have 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1,000.

If you follow these two patterns, then you can count to 1,000! Here are all the numbers
grouped by 100 all the way to 1,000.

Congratulations! You know how to count to 1,000 now!

1 – 3 One More, One Less
Now we are going to learn more about numbers, by finding one more or one less
than a number I give you.
We can use a number line to help us.
First, let’s find one more than a given number. When we say one more it means we
go forwards because the numbers get bigger as we move to the right.
For example,
What number is one more than 9?
Excellent! One more means we go to the right 1 space. So, 10 is one more than 9.
www.aplustutorsoft.com Page 19 of 134
What number is one more than 16?
17 is one more than 16.
What number is one more than 24?
You’re doing a great job! 25 is one more than 24.
What number is one more than 39?
www.aplustutorsoft.com Page 20 of 134
40 is one more than 39. Great job! Keep it up!
What number is one more than 50?
Very good! 51 is one more than 50.
What number is one more than 79?
80 is one more than 79.
www.aplustutorsoft.com Page 21 of 134
You did a fantastic job finding one more. Now, let’s find one less than a number I
give you. When we say one less, it means we go backwards since the numbers get
smaller as we move to the left.
What number is one less than 7?
We go backwards since the numbers get smaller as we move to the left on a
number line. The number 6 is one less than 7.
What number is one less than 20?
www.aplustutorsoft.com Page 22 of 134
Excellent work! 19 is one less than 20.
What number is one less than 39?
38 is one less than 39. You are doing great! Keep it up!
What number is one less than 51?
www.aplustutorsoft.com Page 23 of 134
Very good! 50 is one less than 51.
What number is one less than 82?
Great job! 81 is one less than 82.
What number is one less than 100?
99.

You did an excellent job! Remember, you can go back and review this lesson
again.

1 – 4 Find 10 More
Now let’s practice adding 10 more to any number using mental math. Mental math
means we picture the problem in our heads and then solve it in our heads.
What do you think 10 more means?
Excellent! 10 more means we add 10.
So, 10 more than 1 means 10 + 1.
Now picture 10 + 1 in your head and think about how we know that 10 + 1 is equal to
the next number, which is 11. That’s how you solve a problem using mental math,
great job!
Let’s try another. Ready? What is 10 more than 4?
Excellent job! 10 more than 4 means 10 + 4, which you pictured in your head. You
might have then counted up from 10 four times and got 14. Like this, 10, 11, 12, 13,
14.
You can also stack the numbers and add them in your head. 0 + 4 = 4 and 1 plus
nothing is 1, so you get 14. If you picture this way in your head, be sure not to mix up
the one’s and ten’s places.
www.aplustutorsoft.com Page 26 of 134
Let’s try another problem using this strategy. What is 10 more than 3?
Right! 10 more than 3 means 10 + 3.
So stack the numbers and add them in your head. 0 + 3 = 3 and 1 plus nothing is 1,
which is 13. You are doing great!
What is 10 more than 9?
Right! 10 more than 9 means 10 + 9.
So stack the numbers and add them in your head. 0 + 9 = 9 and 1 plus nothing is 1,
which is 19. Keep it up!
What is 10 more than 10?
Right! 10 more than 10 means 10 + 10.
www.aplustutorsoft.com Page 27 of 134
Stack the numbers and add them in your head. 0 + 0 = 0 and 1 plus 1 is 2, which is
20.
Another way to solve this problem in your head is to know than when adding 10 more,
this means the ten’s place of the other number is increased by 1.
For example, what is 10 more than 23?
If we understand that we just need to add 1 to the ten’s place, then 2 + 1 is 3, so we
have 33.
Let’s check this by stacking the numbers and adding, 3 + 0 = 3 and 2 + 1 = 3. We
have 33, the same number! So, now you know a quicker way to find 10 more.
Let’s try two more using the quick way. What is 10 more than 45?
Excellent job! If we add 1 to the ten’s place, then 4 + 1 is 5, which means 10 more
than 45 is 55.
www.aplustutorsoft.com Page 28 of 134
Last one. What is 10 more than 76?
Excellent job! If we add 1 to the ten’s place, then 7 + 1 is 8, which means 10 more
than 76 is 86.
Great job! If you need more practice, be sure to review this lesson again and keep
memorizing your addition facts.

1 – 5 Number Types
We use numbers three different ways. The first way is to show how many of
something there is. We call these Cardinal numbers. They are also known as the
counting numbers, like 1, 2, 3, 4, 5, 6 and so on.
Some examples of cardinal numbers would be 2 stars, 3 squares, 4 hearts and 5 suns.
The number tells how many of that object we have.
The second way we use numbers are to tell us the order or position of something.
These are called Ordinal numbers. For example, you have already finished 1
st
grade
and now you are in 2
nd
grade. These are ordinal numbers.
The first ten ordinal numbers are:
1st, First
2nd, Second
3rd, Third
4th, Fourth
5th, Fifth
6th, Sixth
7th, Seventh
8th, Eighth
9th, Ninth
10th, Tenth
For example, let’s use the same shapes we used for cardinal numbers. But for ordinal
numbers, let’s outline one of the shapes and you tell me the ordinal number for that
shape.
www.aplustutorsoft.com Page 30 of 134
What is this star’s ordinal number? Right, first.
What is this square’s ordinal number? Very good, second.
What is this heart’s ordinal number? Great job, third.
What is this sun’s ordinal number? Awesome, fourth.
Finally, the last way we use numbers are to identify or name something, like telephone
numbers or jersey numbers.
555-1212
Jersey #18
We call these numbers nominal numbers. Nominal numbers do not tell how many or
show the rank.

1 – 6 Number Forms
In math, numbers can be expressed in several different number forms. Basically, we
can say or write numbers many different ways. In this section we will learn the place
value block form, standard form, expanded form and word form to represent numbers.
Place Value Block Form: This form is often easy to understand since it uses the
“place value” blocks to represent the numbers.
Example #1: Let’s represent the number 234 in Place Value Block Form.
100 100 10 10 10 4
Each of the two large blocks is worth 100 and both of them added together
makes 200.
Each of the three narrow tall blocks is worth 10 and all three added together
makes 30.
The last bar has only 4 blocks, which makes a total of 4.
Adding all these up you get,
200 + 30 + 4 = 234
Standard Form: In standard form the numbers are arranged by their place value. The
standard form is the most common form used to solve math problems, which is why we
call it standard form.
Example #2: The number 134 is written in standard form.
Each digit in this number has a unique place value that depends on the position
of the digit as we discussed in the previous section.
Expanded Form: The expanded form shows the value of each number in the number
set as being added to each other.
Example #3: Write the number 567 in the expanded form.
There are three digits in the number 567, with each number having a special
value. Let’s find the value of each number.
www.aplustutorsoft.com Page 32 of 134
The 5 is in the hundred’s place, so 5 x 100 = 500.
The 6 is in the ten’s place, so 6 x 10 = 60.
The 7 is in the one’s place, so 7 x 1 = 7.
When we add these numbers together, 500 + 60 + 7, we get the number 567.
The number 567 written in expanded form is,
500 + 60 + 7 = 567
Word Form: When a number is in word form it is written using words, just like if you
were reading the number.
Example #4: Write the number 567 in word form.
First say the number and then write it out.
“Five hundred and sixty-seven” is 567 in word form.
Example #5: Write the number 475 in word form.
First say the number and then write it out.
“Four hundred and seventy-five” is 475 in word form.
Example #6: Write the number 5,954 in word form.
First say the number set and then write it out.
“Five thousand, nine hundred and fifty-four” is 5,954 in word form.
Example #7: Write the number 7,054 in word form.
First say the number set and then write it out.
“Seven thousand and fifty-four” is 7,054 in word form.
www.aplustutorsoft.com Page 33 of 134
1 – 7 Even and Odd Numbers
All numbers are either even or odd. Even numbers have partners and odd numbers do
not…like being the odd man out. For example, let’s figure out if the number 6 is odd or
even. Here we have 6 smiley faces. If we give each smiley face a partner, then all the
smiley faces have a partner, making the number 6 even.
Now let’s determine if the number 7 is even or odd. Let’s give each smiley face a
partner.
Do all of the smiley faces have a partner? No, they do not. So, the number 7 is odd
because there is an odd man out.
Here is a chart that shows the even and odd numbers up to 10.
www.aplustutorsoft.com Page 34 of 134
Notice that the numbers take turns being odd and even.
What about larger numbers? How can we tell if the number 74 is even or odd? Well, it
would take a lot of time to partner up such a big number. So, there is an easier way.
All you have to do is look at the last number, which is in the one’s place. If you can
partner up that number then it is even and if not then it is odd.
So, is 74 even or odd? Right, it is even because the number 4 can be partnered up.
Is the number 35 even or odd? Great job! 35 is odd because the number 5 has an
odd man out.
Is the number 92 even or odd? Yes, 92 is even because 2 can be partnered up.
Is the number 80 even or odd? Yes, 80 is even. Even though 0 cannot be partnered
up, the number 10 can be. So, numbers ending in 0 are even.
The easiest way to tell if a number is even or odd is to look at the very last number, the
number that is in the one’s place. Any number that ends in 0, 2, 4, 6 and 8 are even
numbers. And any number that ends in 1, 3, 5, 7 and 9 are odd numbers.
For example, is 112 even or odd? You are right, it is even since the number is the
one’s place is 2.
Is 117 even or odd? You are right, it is odd since the number in the one’s place is 7.
Is 164 even or odd? You are right, it is even since the number in the one’s place is 4.
Is 175 even or odd? You are right, it is odd since the number in the one’s place is 5.
Great job! If you need more practice, please go back and review this lesson.

1 – 8 Introduction to Place Values
Our whole numbering system is based on only 10 numbers, which are also called
digits. We can make any number using just these 10 digits, which are:
0, 1, 2, 3, 4, 5, 6, 7, 8 and 9
We can use these numbers to count up to nine items. But, there are many times we
need to count higher than 9.
For example, I bet you have some blocks at home. Do you think it’s possible you could
have more than 9 blocks, or more than 9 of any toy? Let’s say you have 23 blocks at
home. Did you see how we combined the 2 and 3 to make 23? So, we can use a
combination of those 10 digits to make any other number, like the number 23.
But what does the number 23 mean? What does it mean when the 2 is in this
position?
23
Does it mean 2 or does it mean more than 2? Right, it means more than 2. But how
many more? Let me show you. I made a chart that will help you see the value in the
number 23.
The chart has a ones and a tens column. Now, let’s put the 3 here in the one’s
column since it is the number on the far right. Where do you think the 2 goes? Yes, it
goes in the ten’s column.
www.aplustutorsoft.com Page 36 of 134
This column says we have 3 ones. So, let’s put 3 blocks in this column. 1, 2 and 3.
This column says we have 2 tens. Well, this group represents 1 ten.
What does the ten’s column say we need? Yes, it says we need 2 tens. So, let’s put 2
groups of ten blocks in this column. Great!
Now let’s count all the blocks to see if we hear the number 23. When counting the
tens, we count by 10. Ready?
www.aplustutorsoft.com Page 37 of 134
10, 20, 21, 22, 23
So, we have 2 tens, which have a value of what? 20. And we have 3 ones, which
have a value of what? 3. So, we have 20 + 3, which makes 23.
Let’s try another number, like 52. Do you remember where the 2 goes? Right, the 2
goes in the one’s column. Where does the 5 go? Yes, the 5 goes in the ten’s column.
What is the value of the 5 in this number? Well, to find the value let’s put the same
number of blocks in my handy chart again.
This column says we need what? Yes, 2 ones. So, let’s put 2 blocks here. 1, 2. How
many does the tens column say we need? Yes, we need 5 tens. So, let’s put 5 groups
of 10 in this column.
www.aplustutorsoft.com Page 38 of 134
Now let’s count all the blocks to see if we hear the number 52. When counting the
tens, we count by 10. Ready?
10, 20, 30, 40, 50, 51, 52
So, we have 5 tens, which have a value of what? 50. And we have 2 ones, which
have a value of what? 2. So, we have 50 + 2, which makes 52.
Great job! You have now learned the one’s place value and the ten’s place value.
www.aplustutorsoft.com Page 39 of 134
1 – 9 Identifying Ones and Tens in Numbers
Now let’s see if we can identify tens and ones in numbers. Do the numbers 1 through
9 have any tens?
Excellent! 1 through 9 only has ones.
Remember a ten has 10 ones grouped together like this. 1 ten equals 10 ones and the
numbers 1 through 9 do not have 10 ones.
The numbers from 10 to 19 are composed of 1 ten and some ones.
How many tens and ones are the number 10?
The number 10 has 1 ten and 0 ones.
www.aplustutorsoft.com Page 40 of 134
How many tens and ones are the number 13?
Awesome job! The number 13 has 1 ten and 3 ones.
How many tens and ones are the number 17?
Very good! The number 17 has 1 ten and 7 ones.
www.aplustutorsoft.com Page 41 of 134
How many tens and ones are the number 20?
The number 20 has 2 tens and 0 ones.
How many tens and ones are the number 26?
Excellent work! The number 26 has 2 tens and 6 ones.
How many tens and ones are the number 30?
The number 30 has 3 tens and 0 ones.
www.aplustutorsoft.com Page 42 of 134
How many tens and ones are the number 31?
The number 30 has 3 tens and 0 ones.
How many tens and ones are the number 50?
Yes, the number 50 has 5 tens and 0 ones.
How many tens and ones are the number 65?
Yes, the number 65 has 6 tens and 5 ones.
www.aplustutorsoft.com Page 43 of 134
How many tens and ones are the number 70?
The number 70 has 7 tens and 0 ones.
How many tens and ones are the number 84?
Yes, the number 84 has 8 tens and 4 ones.
How many tens and ones are the number 90?
The number 90 has 9 tens and 0 ones.
www.aplustutorsoft.com Page 44 of 134
How many tens and ones are the number 99?
Yes, the number 99 has 9 tens and 9 ones.
You did a very good job! If you need more practice identifying the tens and ones in
numbers, then please go back and review this lesson again.

1 – 10 Place Values for 3-digit Numbers
We have talked about how our numbering system is based on only 10 digits and we
can make any number using just these 10 digits, which are:
0, 1, 2, 3, 4, 5, 6, 7, 8 and 9
We have also learned how to find the value of a number, like 23. Do you remember
putting the 3 in the one’s column and the 2 in the ten’s column? Then, we used blocks
to find their value, meaning the 2 means 2 tens with a value of 20 and the 3 means 3
ones with a value of 3, making 23.
Similar to this, we can make a number that has more than 2 digits. Let’s use the
number one hundred thirty-five. How many digits are in 135? Yes, 1, 3 and 5 are
digits, so there are 3 digits. So, what is the name of the place value for the 1? Let’s
say the number again, one hundred thirty-five. Can you hear how we say the place
value in the number? Listen closely, one hundred thirty-five. Yes, the 1 is in the
hundred’s place. So, now we have a new chart to help us figure out the value of each
digit.
www.aplustutorsoft.com Page 46 of 134
Do you remember where the 5 goes? Right, the 5 goes in the one’s column. Where
does the 3 go? Yes, the 3 goes in the ten’s column. Now, where do you think the 1
goes? Good job! The 1 goes in the hundred’s column.
Now we want to know the value of each digit. So we can put the same number of
blocks in this handy chart again.
This column says we need what? Yes, 3 ones. So put 3 blocks here. 1, 2, 3. How
many does the tens column say we need? Yes, we need 3 tens. So, let’s put 3 groups
of 10 in this column. 10, 20, 30. Now, how many does the hundred’s column say?
Great job! We need 1 hundred, which is the same as 10 tens.
This block has 10 tens altogether, which makes 100. Let’s count each column of 10.
Remember how to skip count by 10? Good. Please count with me. 10, 20, 30, 40, 50,
60, 70, 80, 90 and 100. So, 10 tens make 100.
www.aplustutorsoft.com Page 47 of 134
Now let’s count all the blocks to see if we hear the number 135. Ready?
100, 110, 120, 130, 131, 132, 133, 134, 135
So, we have 1 hundreds, which has a value of 100. We have 3 tens, which have a
value of 30. And we have 5 ones, which have a value of 5. So, we have 100 + 30 + 5,
which makes 135.
Let’s try one more example. Let’s use the number 248. Do you remember where the 8
goes? Right, the 8 goes in the one’s column. Where does the 4 go? Yes, the 4 goes
in the ten’s column. Now, where do you think the 2 goes? Good job! The 2 goes in
the hundred’s column.
www.aplustutorsoft.com Page 48 of 134
Now we want to know the value of each digit. How can we do that? Yes, we can put
the same number of blocks in this handy chart again.
The ones column says we need what? Yes, 8 ones. So put 8 blocks here. 1, 2, 3, 4,
5, 6, 7, 8. How many does the tens column say we need? Yes, we need 4 tens. So,
let’s put 4 groups of 10 in this column. 10, 20, 30, 40. Now, how many does the
hundreds column say we need? Great job! We need 2 hundreds. 100, 200.
So, now let’s count all the blocks to see if we hear the number 248. Ready?
100, 200, 210, 220, 230, 240, 241, 242, 243, 244, 245, 246, 247, 248
Great job! So, we have 2 hundreds, which has a value of 200. We have 4 tens, which
have a value of 40. And we have 8 ones, which have a value of 8. So, we have 200 +
40 + 8, which makes 248.
Great job! You have now learned the one’s place value, the ten’s place value and the
hundred’s place value.

1 – 11 Number Combinations (up to 3 digits)
Numbers can be combined many different ways. Now that you know the one’s, ten’s
and hundred’s place values, you can now make different number combinations. Let
me show you what I mean.
Let’s take a look at the number 34 using my handy little chart that shows the one’s and
ten’s place.
Now, do you remember where the 4 goes? The 4 goes in the one’s place. Where
does the 3 go? Great job! The 3 goes in the ten’s place.
What does the ones column say we need? Yes, we need 4 ones. So, let’s put 4
blocks in this column. 1, 2, 3, 4. Now, what does the tens column say? Very good! It
says we need 3 tens. So, let’s put 3 groups of ten blocks in this column. 1, 2, 3.
www.aplustutorsoft.com Page 50 of 134
So, now let’s count all the blocks to see if we hear the number 34. Remember, we
count by 10. Ready?
10, 20, 30, 31, 32, 33, 34
Great job! So, we have 3 tens, which have a value of 30. And we have 4 ones, which
have a value of 4. So, we have 30 + 4, which makes 34.
So, that is the number 34 where we used the combination of 3 tens and 4 ones.
Now let’s make a different number combination for the number 34. Let’s move 1 of
those tens over to the one’s place.
www.aplustutorsoft.com Page 51 of 134
Do you see how we have a different number combination now? If we count the blocks,
the one’s column says we have 14 ones and the ten’s column says we have 2 tens.
When we moved 1 ten over to the ones, we had to subtract 10 from the 30 in the ten’s
column and add 10 to the 4 in the one’s column. Let’s add 2 tens, which is 20 to 14
ones, which is 14. So, 20 + 14 equals 34. It’s the same number, just a different
number combination.
Let’s try another number, like 48. Ok, do you know where the 8 goes? Great, the 8
goes in the ones. Let’s go ahead and put 8 blocks there. Do you remember where the
4 goes? Right, the 4 goes in the tens. So, let’s put 4 groups of ten there.
So, now let’s count all the blocks to see if we hear the number 48. Ready?
10, 20, 30, 40, 41, 42, 43, 44, 45, 46, 47, 48
Great job! So, the number combination we have for 48 is 4 tens and 8 ones.
Now let’s make a different number combination for 48. Let’s move 1 of those tens over
to the one’s place.
www.aplustutorsoft.com Page 52 of 134
Can you tell me what different number combination we made of 48? Great job! 3 tens
and 18 ones.
If we count the blocks, the one’s column says we have 18 ones and the ten’s column
says we have 3 tens. When we moved 1 ten over to the ones, we had to subtract 10
from the 40 in the ten’s column and add 10 to the 8 in the one’s column. Let’s add 3
tens, which is 30 to 18 ones, which is 18. So, 30 + 18 equals 48. It’s the same
number, just a different number combination.
Let’s try one more, but this time with 3 digits. Let’s write a number combination for
123. The 3 goes in the one’s column and the 2 goes in the ten’s column. Do you
remember where the 1 goes?
Very good! The 1 goes in the hundred’s column. So, we have 3 ones, 2 tens and 1
hundred.
www.aplustutorsoft.com Page 53 of 134
Now let’s make a different number combination for 123. Let’s move 1 hundreds over to
the ten’s place.
Do you know what different number combination we made for 123? Awesome job! We
now have 0 hundreds, 12 tens and 3 ones.
When we moved 1 group of 100 over to the ten’s place, that left nothing in the
hundred’s column. Remember, 1 group of 100 equals 10 tens, so we had to add 10
tens to the 2 tens that was already there. What is 10 + 2? Right! 12. So we have 12
tens in the ten’s column now. The one’s column did not change, so we still have 3
ones.
www.aplustutorsoft.com Page 54 of 134
So, the first number combination for 123 was 1 hundred, 2 tens and 3 ones.
The second number combination for 123 was 12 tens and 3 ones.
Great job! You know how to make different number combinations now! If you don’t
fully understand then please go back and watch it again.

1 – 12 The Role of Zero
This is the number zero.
The number zero is very important in math because it has many jobs to do and we are
going to talk about two of them.
The first job zero has is to represent nothing.
For example, let’s say you have 3 cookies and you ate all of them. How many do you
have left?
Right! Now, you have nothing left. You can also say you have zero cookies left.
The second job zero has is to be a place value holder.
To better explain this, let’s look at the number 1. In fact, many believe that the number
one is the first number. What do you think?
www.aplustutorsoft.com Page 56 of 134
Well, let’s look at an example. When someone wins a 100 meter race they say they
won first place.
However, when the runners begin the 100 meter race, they start at 0 meters. So, really
0 is first.
Another example is where we start counting. We start counting with the number one.
However, let’s say we are counting pennies. We actually start with no pennies or zero
pennies and count up from there saying 1 first. But zero is really the first number.
www.aplustutorsoft.com Page 57 of 134
Our number system is based on 10 numbers, starting with zero and ending with 9.
This is how we represent the numbers 0 through 9. Each square is worth 1, so 1
through 9 only has ones.
A ten has 10 ones grouped together like this.
The number 10 equals 1 ten and 0 ones.
The number 10 uses the numbers 0 and 1 combined to show it is bigger than 9 ones.
But why does 1 come first and 0 second? Right, because a very important job 0 has is
to be a place holder. Zero’s job is to tell the numbers 1-9 that 10 is bigger by moving
the 1 over a place value to the ten’s place.
www.aplustutorsoft.com Page 58 of 134
Zero is also a place value holder for the numbers 20, 30, 40, 50 and so on.
This is a really important job.
What if we put zero before the number. What does zero-one mean?
As long as it is just the numbers 01, it means 1. Why?
Well, let’s put zero-one in our place value chart. Zero goes in the ten’s column and 1
goes in the one’s column. How many squares do we have? Right, one!
www.aplustutorsoft.com Page 59 of 134
What does zero-seven mean?
Excellent job! Zero-seven is the same as 7.
We can check this by using our place value chart. Zero goes in the ten’s column and 7
goes in the one’s column. How many squares do we have? Right, seven!
What does seven-zero mean?
www.aplustutorsoft.com Page 60 of 134
Very good! Seven-zero is the same as 70.
We can check this by using our place value chart. Seven goes in the ten’s column and
0 goes in the one’s column. How many squares do we have? Right, seventy!
What if we put a 0 before 70, does it change the value?
Well, let’s add a column to the left in our place value chart for the zero. Did it change
how many squares we have? No, great job! We still have 70.
Great job! If you need more practice, please go back and review this lesson again.

1 – 13 Place Value for Larger Numbers
The first numbering system was invented by two Mathematicians from India in the 4
th
century, which are the years from 301 to 400. They introduced a numbering system
based on the positions of a digit or the place value of a number within any number set,
such as the position or place value of the number 3 in the number set 103.
Today, the most common numbering system uses the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8
and 9. This modern number system is based on the power of 10. Any number can be
written using a combination of these 10 numbers and each number in a number set
has a special position or place value.
The place value is the value of the place a particular number has in a given number
set. The place value of 3 in 103 is the one’s place.
Example #1: Let’s first find each number’s position or place value in the number
set 654,321.
The 1 is the first digit on the far right and is in the one’s place.
The 2 is the second digit from the right and is in the ten’s place.
The 3 is the third digit from the right and is in the hundred’s place.
The 4 is the fourth digit from the right and is in the thousand’s place.
The 5 is the fifth digit from the right and is in the ten thousand’s place.
The 6 is the sixth digit from the right and is in the hundred thousand’s place.
It is very important that you can say the place value of each number in a given number
set. Each number in a number set represents a special value based on its position
within the number set. Now, let’s use the same number above and find the value of
each number’s position.
www.aplustutorsoft.com Page 62 of 134
Example #2: Let’s find the value of each number’s position or place value in the
number set 654,321.
To find the number’s value, multiply the number by the place value.
The one’s place means multiply by one.
The ten’s place means multiply by ten.
The hundred’s place means multiply by one hundred.
The thousand’s place means multiply by one thousand.
The ten thousand’s place means multiply by ten thousand.
The one hundred thousand’s place means multiply by one hundred
thousand.
And so on.
So, continuing from Example #1:
The number 1 is in the one’s place, 1 x 1 = 1.
The number 2 is in the ten’s place, 2 x 10 = 20.
The number 3 is in the hundred’s place, 3 x 100 = 300.
The number 4 is in the thousand’s place, 4 x 1,000 = 4,000.
The number 5 is in the ten thousand’s place, 5 x 10,000 = 50,000.
The number 6 is in the hundred thousand’s place, 6 x 100,000 = 600,000.
If we add all these numbers together, we would get 654,321.
Example #3: What place value does the number 9 have in the number set
64,892?
If you answered the ten’s place, then you are correct!
The number 9 is the second digit from the right in the ten’s place.
Example #4: What value does the number 9 have in the number set 64,892?
If you answered 90, then you are correct!
The number 9 is in the ten’s place, so you multiply 9 by 10 to get 90.

Example #5: What place value does the number 4 have in the number set
64,892?
If you answered the thousand’s place, then you are correct!
The number 4 is the fourth digit from the right in the thousand’s place.
Example #6: What value does the number 4 have in the number set 64,892?
If you answered 4,000 then you are correct!
The number 4 is in the thousand’s place, so you multiply 4 by 1,000 to get 4,000.

1 – 14 Number Combinations for Larger Numbers
In mathematics, there are many different ways numbers can be combined. It is
important to understand place values when figuring different number combinations.
One’s Place Multiply by 1
Ten’s Place Multiply by 10
Hundred’s Place Multiply by 100
Thousand’s Place Multiply by 1,000
Ten Thousand’s Place Multiply by 10,000
Hundred Thousand’s Place Multiply by 100,000
654,321
Example #1: Let’s see some different combinations we can make out of 427.
Combination #1: 4 hundreds, 2 tens and 7 ones
Combination #2: 4 hundreds, 1 ten and 17 ones
Combination #3: 3 hundreds, 12 tens and 7 ones
Combination #4: 2 hundreds, 22 tens and 7 ones
Let’s take a closer look at how we came up with these number combinations.
Combination #1: 4 hundreds, 2 tens and 7 ones
This number combination is the easiest to figure out.
4 hundreds, so 4 is multiplied by 100.
4 x 100 = 400
2 tens, so 2 is multiplied by 10.
2 x 10 = 20
7 ones, so 7 is multiplied by 1.
7 x 1 = 7
Let’s add these together to see if we get 427.
400 + 20 + 7 = 427
So, 427 is the same as 4 hundreds, 2 tens and 7 ones.
Combination #2: 4 hundreds, 1 ten and 17 ones
This number combination is a little harder because we are taking away from
one place value and adding it to another place value.
4 hundreds, so 4 is multiplied by 100.
4 x 100 = 400
www.aplustutorsoft.com Page 65 of 134
1 ten, so 1 is multiplied by 10.
1 x 10 = 10
17 ones, so 17 is multiplied by 1.
17 x 1 = 17
Note: 1 ten equals 10 ones, so we took away 1 ten from the ten’s
place and added 10 ones to the one’s place.
Let’s add these together to see if we get 427.
400 + 10 + 17 = 427
So, 427 is the same as 4 hundreds, 1 ten and 17 ones.
Combination #3: 3 hundreds, 12 tens, and 7 ones
3 hundreds, so 3 is multiplied by 100.
3 x 100 = 300
12 tens, so 12 is multiplied by 10.
12 x 10 = 120
Note: 1 hundred equals 10 tens, so 1 hundred was taken from the
hundreds place and 10 tens added to the ten’s place.
7 ones, so 7 is multiplied by 1.
7 x 1 = 7
Let’s add these together to see if we get 427.
300 + 120 + 7 = 427
So, 427 is the same as 3 hundreds, 12 tens and 7 ones.
Combination #4: 2 hundreds, 22 tens, and 7 ones
2 hundreds, so 2 is multiplied by 100.
2 x 100 = 200
22 tens, so 22 is multiplied by 10.
22 x 10 = 220
Note: 2 hundreds equals 20 tens, so 2 hundreds were taken from the
hundred’s place and 20 tens added to the ten’s place.
7 ones, so 7 is multiplied by 1.
7 x 1 = 7
www.aplustutorsoft.com Page 66 of 134
Let’s add these together to see if we get 427.
200 + 220 + 7 = 427.
So, 427 is the same as 2 hundreds, 22 tens and 7 ones.
Now that you know how to make different number combinations based on place value,
you can also learn how to say numbers differently.
Example #2: The following are two ways to write 1,256.
One thousand two hundred fifty-six
Let’s check this.
1 thousand, so 1 is multiplied by 1,000.
1 x 1,000 = 1,000
2 hundreds, so 2 is multiplied by 100.
2 x 100 = 200
5 tens, so 5 is multiplied by 10.
5 x 10 = 50
6 ones, so 6 is multiplied by 1.
6 x 1 = 6
Now, let’s add them up.
1,000 + 200 + 50 + 6 = 1,256
Clearly, we can write 1,256 as one thousand two hundred fifty-six.
Twelve hundred fifty-six
Let’s check this:
12 hundreds, so 12 is multiplied by 100.
12 x 100 = 1,200
Note: 1 thousand equals 10 hundreds, so 1 thousand was taken from
the thousand’s place and 10 hundreds added to the hundred’s place.
5 tens, so 5 is multiplied by 10.
5 x 10 = 50
6 ones, so 6 is multiplied by 1.
6 x 1 = 6
Now, let’s add them up.
1,200 + 50 + 6 = 1,256
So, we can also write 1,256 as twelve hundred fifty-six.

1 – 15 Defining and Grouping Whole Numbers
Whole Numbers: A whole number is any number, or integer, greater than or equal to
zero. An integer is a number without a fractional part or decimal point. Any number in
the following set of numbers is considered a whole number.
{0, 1, 2, 3, 4, 5, …}
Whole numbers are often called the “counting numbers”.
The number 1,543 is a whole number.
The number 12.5 is not a whole number because there is a decimal point in front of the
number 5.
Grouping Large Numbers: When numbers get really large they can be harder to
read. To make large numbers easier to read, we group the numbers by three starting
from the right or the one’s place.
Example #1: Group the numbers in the number set 24675.
We group large numbers by separating sets of 3 numbers by commas. So, in
the number 24675, we start on the right in the one’s place and count 3 places to
the left and place a comma. So, a comma would be placed between the 4 and 6
in the number.
So, the number 24675 is written as 24,675.
Example #2: Group the numbers in the number set 675342?
Starting in the one’s place and counting 3 places to the left, the comma would be
placed between the numbers 5 and 3.
So, the number 675342 is written as 675,342.
Example #3: Group the numbers in the number set 5872?
Starting in the one’s place and counting 3 places to the left, the comma would be
placed between the numbers 5 and 8.
So the number 5872 is written as 5,872.
Example #4: Group the numbers in the number set 87654321.
www.aplustutorsoft.com Page 68 of 134
Starting in the one’s place and counting 3 places to the left, the comma would be
placed between the numbers 4 and 3.
Now we have 87654,321. Do you see how we could put in another comma
since we have more than 3 numbers in a row without a comma?
Counting 3 more places from our first comma, we can put another comma
between the numbers 7 and 6.
So, the number 87654321 is written as 87,654,321.
