1.This picture illustrates the division 6 ÷ 3 = 2. b) Draw a picture that illustrates 9 ÷ 3 = 3. c) Draw a picture that illustrates 15 ÷ 3 = 5. |

2.a Draw a picture to illustrate 1 ÷ 3 = ?? In other words, you have one whole pie. You want to divide that pie equally between 3 people. How much pie does each one get to eat? Think!
b. Draw a picture to illustrate 1 ÷ 4. You have _ pie, and __ people. How much pie does each one get?
c. Draw a picture to illustrate 1 ÷ 5. You have _ pie, and __ people. How much pie does each one get?

3. a. Draw a picture to illustrate 2 ÷ 5. You have __ pies, and __ people. How much pie for each?
b. Draw a picture to illustrate 3 ÷ 5. You have __ pies, and __ people. How much pie for each?
e. Draw a picture to illustrate 4 ÷ 3. How much pie does each one get to eat?

4. Everyone gets 6 apples and 1 is left over. 25 ÷ 4 = 6 R1.
What if you take your knife and ALSO divide the remainder apple between those
four people?
5. In these division problems you will have a remainder. Use the knife and divide the remainder too!
| 13 ÷ 2 = | 9 ÷ 2 = |
16 ÷ 3 = |
