Multiplication and times tables worksheet

Part A: Working out and filling in

1. 1. 2, 3, 6

   Count the plates first, then how many are on one plate. The total is that many lots of that number.

   2 plates of 3 is 2 lots of 3: 6.

2. 2. 5 × 2 = 10

   5 × 2: ×2 is a double, 5 + 5 = 10

3. 3. 10 × 1 = 10

   10 × 1: times 1 leaves a number as it is, so it's 10

4. 4. 15, 15

   Start with the rows: 5 rows of 3. Looking the other way doesn't change how many there are.

   Nothing has changed, so both ways give 15: 3 × 5 = 5 × 3 = 15.

5. 5. 35

   How are 5 × 7 and 7 × 5 related? There's no need to work it out again.

   5 × 7 is 7 × 5 the other way round: 35.

6. 6. 3 × 1 = 3

   3 × 1: times 1 leaves a number as it is, so it's 3

7. 7. 6 × 11 = 66

   6 × 11: ×6 is ×3 doubled, 11 × 3 = 33, 33 × 2 = 66

8. 8. 6 × 7 = 42

   6 × 7: ×7 is ×5 and ×2, 6 × 5 = 30, 6 × 2 = 12, 30 + 12 = 42

9. 9. 8 × 11 = 88

   8 × 11: a single digit ×11 is the digit twice, 8 × 11 = 88

10. 10. 9 × 6 = 54

    9 × 6: ×9 is ×10 minus one lot, 6 × 10 = 60, 60 − 6 = 54

11. 11. 8

    Think about just one top first: how many skirts can it go with? Every top has the same number.

    Each top goes with 4 skirts, so 2 tops give 2 lots of 4: 2 × 4 = 8.

Part B: Choose, or true or false

1. 12. False

   5 lots of 7 is 7 × 5. Work that out first, then compare it with 28.

   Adding 7 5 times gives 35: 7 × 5 = 35.

Part C: Word problems

Marking: 2 for the working, 1 for the answer, 1 for the sentence.

1. 13. It takes Chi-keung 4 minutes to walk from home to the park. How many minutes does he walk to the park and back home again? (Answer: 8 minutes)

   One way there, one way back: 2 lots of 4; 2 × 4 = 8

2. 14. 5, 10

   2 rows of 5: what do you see if you look down the columns instead? The number of counters stays the same.

   2 rows of 5 seen the other way is 5 rows of 2: 5 × 2 = 2 × 5 = 10.

3. 15. The chairs in a hall are set out in 7 rows of 4. How many chairs are there altogether? (Answer: 28 chairs)

   4 × 7 = 28

4. 16. An octopus has 8 arms. An aquarium has 9 octopuses. How many arms do they have altogether? (Answer: 72 arms)

   8 × 9 = 72

5. 17. The chairs in a hall are set out in 5 rows of 7. How many chairs are there altogether? (Answer: 35 chairs)

   7 × 5 = 35

6. 18. 15 ways

   Pick one path to the park: how many ways are there on to the library? Every path to the park gives the same choice.

   Each path to the park joins any of the 5 paths on: 3 × 5 = 15.
