Same three numbers, two directions. Write the missing number in each box.

12. The family of 3, 9, 27

3 × = 27 27 ÷ 3 = 27 ÷ = 3

13. The family of 4, 6, 24

4 × 6 = 24 ÷ 4 = 24 ÷ = 4

14. The family of 7, 8, 56. Write all four equations yourself.

If you know one multiplication fact, you also know two division facts.

Division Within 100

Build it

1. Each group: 3, left over: 1 · 2. Full bags: 3, left: 2

Draw it

3. Tops: 10 and 3, so 52 ÷ 4 = 13

Numbers only

4. 9 5. 9 6. 5 7. 9
8. 7 R1 9. 8 R2 10. 6 R4 11. 8 R5

12. 3 × 9 = 27 27 ÷ 3 = 9 27 ÷ 9 = 3
13. 4 × 6 = 24 24 ÷ 4 = 6 24 ÷ 6 = 4
14. 7 × 8 = 56, 8 × 7 = 56, 56 ÷ 7 = 8, 56 ÷ 8 = 7

The leftover counter in problem 1 is the point of the page: a remainder is a real object that did not fit into a group. Students who see that do not write "7 remainder 1" as "71".
