Answer division problems in class

And so much more!

How do you divide?

There is more than one way to find the answer to a division problem! Did you know… There is more than one way to find the answer to a division problem!

Let’s try 12 ÷ 4

How many cookies are in each group? 12 ÷ 4 Split 12 cookies evenly into 4 groups. How many cookies are in each group?

There are 3 cookies in each group. 12 ÷ 4 There are 3 cookies in each group. 12 ÷ 4 = 3

6 ÷ 2 Split the 6 triangles up evenly into the 2 cups How many triangles go in each cup?

There are 3 triangles in each cup. 6 ÷ 2 There are 3 triangles in each cup. 6 ÷ 2 = 3

Now YOU Try!

4 ÷ 2 Split the 4 triangles up evenly into the 2 cups How many triangles go in each cup? A. 1 B. 2 C. 3 D. 4

6 ÷ 3 Split the 6 triangles up evenly into the 3 cups How many triangles go in each cup? A. 4 B. 3 C. 2 D. 6

8 ÷ 2 Split the 8 triangles up evenly into the 2 cups How many triangles go in each cup? A. 1 B. 2 C. 3 D. 4

9 ÷ 3 Split the 9 triangles up evenly into the 3 cups How many triangles go in each cup? A. 9 B. 3 C. 2 D. 6

Division and Multiplication are Opposites! Did you know that the same three numbers that are used to multiply are used to divide? For example: 12 ÷ 3 = 4 and 4 x 3 = 12 12 ÷ 4 = 3 and 3 x 4 = 12 The numbers 3, 4, and 12 are a fact family

Fact Family A fact family is a collection of related multiplication and division facts made from the same numbers. 6 7 42 6 x 7 = 42 42 ÷ 7 = 6 7 x 6 = 42 42 ÷ 6 = 7

Fact Families 12 ÷ 4 = x 4 = 12 12 ÷ 4 = 4 x = 12 12 ÷ = 4 = Fact Family: 3, 4, 12 3

Now YOU Try!

Which number belongs in the yellow box? Fact Families 20 ÷ 5 = 6 x 5 = 20 20 ÷ 5 = 6 5 x 6 = 20 20 ÷ 6 = 5 = ? Which number belongs in the yellow box? A. 5 B. 4 C. 20 D.10

Which number belongs in the yellow box? Fact Families 35 ÷ 7 = 6 x 7 = 35 35 ÷ 7 = 6 7 x 6 = 35 35 ÷ 6 = 7 = ? Which number belongs in the yellow box? A. 5 B. 7 C. 6 D.1

Which number belongs in the yellow box? Fact Families 24 ÷ 2 = 6 x 2 = 24 24 ÷ 2 = 6 2 x 6 = 24 24 ÷ 6 = 2 = ? Which number belongs in the yellow box? A. 12 B. 4 C. 24 D. 2

6 ÷ 2 = 3 Oops! Try Again. There are 3 cookies in each cup. Remember to split the triangles evenly between the cups For example, 6 ÷ 2 There are 3 cookies in each cup. 6 ÷ 2 = 3

Oops! Remember… A fact family is a collection of related multiplication and division facts made from the same numbers. 6 7 42 6 x 7 = 42 42 ÷ 7 = 6 7 x 6 = 42 42 ÷ 6 = 7
