Teaching: Multiplication is Repeated Addition
Repeated addition means adding the same number again and again.
If we have 3 groups with 4 objects in each group, we can add 4 + 4 + 4. This is the same as 3 x 4.
Group 1
Group 2
Group 3
4 + 4 + 4 = 12
3 x 4 = 12
Interactive: Build Equal Groups
Click to show 4 groups of 3.
Using x and =
The multiplication sign x means groups of.
x
means groups of
=
means the same as
5 x 2 means 5 groups of 2. The answer is called the product.
5 x 2 = 10
Activity: Repeated Addition to Multiplication
Which multiplication sentence matches 2 + 2 + 2 + 2?
2 + 2 + 2 + 2 = 8
4 x 2 = 8
2 x 2 = 4
8 x 2 = 16
Activity: Multiply One Digit Numbers
Find the product.
6 x 5 = ?
25
30
35
Type the Multiplication Answer
Type the answer for 7 times 4.
7 x 4 = ?
Teaching: Division is Sharing or Grouping
Division means sharing equally or making equal groups.
If we share 10 objects between 2 children, each child gets 5 objects. That is 10 divided by 2 equals 5.
Child 1
Child 2
10 ÷ 2 = 5
Division as Repeated Subtraction
We can divide by taking away the same number again and again.
To divide 12 by 2, we can keep subtracting 2 until nothing is left: 12, 10, 8, 6, 4, 2, 0. We subtracted 2 six times.
12 - 2 - 2 - 2 - 2 - 2 - 2 = 0
12 ÷ 2 = 6
Interactive: Share Even Numbers by 2
Click to share 14 counters equally between 2 groups.
Group 1
Group 2
Using ÷ and =
The division sign means divide or share.
÷
means divide or share
=
means the same as
18 ÷ 2 = 9
Activity: Divide by 2
Divide the even number by 2.
24 ÷ 2 = ?

14
Type the Division Answer
Type the answer for 50 divided by 2.
50 ÷ 2 = ?
Teaching: Division Reverses Multiplication
Multiplication and division are related.
If 6 x 2 = 12, then 12 ÷ 2 = 6. Division takes us back to the number of groups.
6 x 2 = 12
Multiplication makes the total.
↔
Reverse
12 ÷ 2 = 6
Division takes us back.
Activity: Reverse the Multiplication
If 8 x 2 = 16, what is 16 divided by 2?
8 x 2 = 16
16 ÷ 2 = ?
