1. Answer to Question 1

   1. There are 3 groups with 5 in each group. Count in 5s, one jump per group: 5, 10, 15. So 3 × 5 = 15.
   2. There are 4 groups with 3 in each group. Count in 3s: 3, 6, 9, 12. So 4 × 3 = 12.
   3. There are 6 groups with 2 in each group. Count in 2s: 2, 4, 6, 8, 10, 12. So 6 × 2 = 12. Different groups can give the same total.

2. Answer to Question 2

   1. 5 × 10 = 50 sweets.
   2. 30 ÷ 5 = 6 pencils in each pot, because 6 × 5 = 30.
   3. 8 × 2 = 16 children.
   4. 18 ÷ 2 = 9 boxes, because 9 × 2 = 18.

3. Answer to Question 3

   1. Sharing. 15 ÷ 3 = 5 apples each.
   2. Grouping. 15 ÷ 5 = 3 bags.
   3. Grouping. 20 ÷ 4 = 5 pots.
   4. Sharing. 20 ÷ 4 = 5 pens in each pot.

4. Answer to Question 4

   1. The whole bar is 18 and it is cut into 3 equal parts. Ask: what number added three times makes 18? 6 + 6 + 6 = 18, so each part is 6: 18 ÷ 3 = 6.
   2. The whole bar is 40, cut into 4 equal parts. 10 + 10 + 10 + 10 = 40, so each part is 10: 40 ÷ 4 = 10.
   3. Multiply the size of one part by the number of parts to get back to the whole: 3 × 6 = 18 and 4 × 10 = 40. Multiplication is the inverse of division.

5. Answer to Question 5

   1. 14 ÷ 2 = 7, so the missing number is 7.
   2. 40 ÷ 5 = 8, so the missing number is 8.
   3. 6 × 5 = 30, so the missing number is 30.
   4. 30 ÷ 3 = 10, so the missing number is 10.
   5. 80 ÷ 10 = 8, so the missing number is 8.

6. Answer to Question 6

   1. 4 × 3 = 12, 12 ÷ 3 = 4, 12 ÷ 4 = 3.
   2. 6 × 5 = 30, 30 ÷ 5 = 6, 30 ÷ 6 = 5.
   3. 9 × 10 = 90, 90 ÷ 10 = 9, 90 ÷ 9 = 10.

7. Answer to Question 7

   1. 5 × 6 = 30 eggs.
   2. 2 × 6 = 12 eggs.
   3. 30 − 12 = 18 eggs.
   4. 18 ÷ 3 = 6 boxes, because 6 × 3 = 18.

8. Answer to Question 8

   1. 30 ÷ 5 = 6 sweets, because 6 × 5 = 30.
   2. 5 × 2 = 10 sweets.
   3. 30 − 10 = 20 sweets.
   4. 30 ÷ 10 = 3 bags.

9. Answer to Question 9

   1. 40 ÷ 5 = 8 teams.
   2. 8 × 2 = 16 balls.
   3. 24 ÷ 8 = 3 bibs each, because 3 × 8 = 24.
   4. 40 ÷ 10 = 4, so yes, the coach is right.

10. Answer to Question 10

    1. 12 × 4 = 48 seats.
    2. 12 − 2 = 10 rows for children. 10 × 4 = 40 seats.
    3. There are 40 seats and 32 children. 40 is more than 32, so yes.
    4. 40 − 32 = 8 empty seats.

11. Answer to Question 11

    1. 4 × 10 = 40 biscuits.
    2. 40 − 3 = 37 biscuits.
    3. 40 ÷ 5 = 8 biscuits in each tin.
    4. 5 × 10 = 50 and 40 is less than 50, so yes, there is room, with space for 10 more.

12. Answer to Question 12

    1. There are 6 rows with 5 plants in each. Count in 5s six times: 5, 10, 15, 20, 25, 30. So 6 × 5 = 30 plants.
    2. He plants 3 rows of 5 tomatoes: 3 × 5 = 15 tomato plants.
    3. Add the two groups: 30 + 15 = 45 plants before the storm.
    4. 7 plants are damaged: 45 − 7. Take 5 to get 40, then 2 more to get 38 undamaged plants.

13. Answer to Question 13

    1. 9 × 2 = 18 shoes.
    2. 9 + 7 = 16 boxes.
    3. 16 − 4 + 10 = 22 boxes.
    4. 22 × 2 = 44 shoes.

14. Answer to Question 14

    1. Each page holds 10 stickers and there are 8 pages: 8 × 10 = 80 stickers. Multiplying by 10 moves the digit into the tens place.
    2. 3 whole pages are full: 3 × 10 = 30 stickers already in the album.
    3. Take the full spaces away from the total: 80 − 30 = 50 more stickers can fit.
    4. He sticks in 25 of those 50 spaces: 50 − 25 = 25 empty spaces are left. That is exactly half of the free spaces.

15. Answer to Question 15

    1. 4 × 5 = 20 teams.
    2. 20 × 4 = 80 children.
    3. 80 ÷ 5 = 16 races.
    4. 16 × 2 = 32 cones.
    5. 32 ÷ 10 is 3 with 2 left over. 3 packs hold 30 cones, which is not enough, so she needs 4 packs.

16. Answer to Question 16

    1. 6 × 5 = 30 carrots.
    2. 8 × 2 = 16 scoops.
    3. 4 × 10 = 40 pieces of hay.
    4. For 2 days: 30 × 2 = 60 carrots. 60 ÷ 10 = 6 bags.
    5. The guinea pigs eat 40 pieces and the rabbits eat 30 carrots. 40 is more than 30, so it is true.

17. Answer to Question 17

    1. 30 × 2 = 60 sandwiches.
    2. 30 ÷ 6 = 5 packs, because 5 × 6 = 30.
    3. 30 × 5 = 150 grapes. 150 ÷ 50 = 3 bags.
    4. 4 × 10 = 40 cakes. 40 is more than 30, so yes.
    5. 40 − 30 = 10 cakes left over.

18. Answer to Question 18

    1. 5 × 8 = 40 bricks.
    2. 4 × 10 = 40 bricks.
    3. 40 + 40 = 80 bricks.
    4. 80 ÷ 20 = 4 boxes, because 4 × 20 = 80.
    5. Both walls have 40 bricks. Neither wall has more, so the difference is 0.

19. Answer to Question 19

    1. 4 × 5 = 20 swimmers.
    2. 3 × 20 = 60 swimmers.
    3. 60 ÷ 10 = 6 packs.
    4. 3 × 2 = 6 lifeguards.
    5. 6 × 3 = 18 bottles.

20. Answer to Question 20

    1. Work backwards. 28 − 3 = 25 and 25 ÷ 5 = 5. The number is 5. Check: 5 × 5 = 25 and 25 + 3 = 28.
    2. Try pairs that multiply to 24: 1 × 24, 2 × 12, 3 × 8 and 4 × 6. Only 4 + 6 = 10. The numbers are 4 and 6.
    3. 20 ÷ 6 is 3 with 2 left over (3 × 6 = 18). The sweets cannot be shared equally, so Sam is not right.
    4. For example: "There are 4 plates with 5 biscuits on each plate. How many biscuits?" 4 × 5 = 20. "20 biscuits are shared between 4 plates. How many on each plate?" 20 ÷ 4 = 5.
