### Using Our Maths B

#### Following Units 9-11

These activities bring together the different mathematical skills that your child should now know. By combining these skills in puzzles and activities your child will need to reason and think of solutions, as well as complete calculations. This will help your child to really understand the skills they are learning.

Talk through each group of questions and ask your child how they are going to solve the challenges.

It’s good to get stuck sometimes! When this happens discuss the challenge in the following order:

- What do we need to find out to solve the challenge?
- What do we know by looking at the question?
- Want could we do first?
- How would that help us?

Is there anything else we could do?

#### Activities: Target numbers

Answer: **Using Our Maths B Answers (PDF)**

Without a calculator create a calculation with the following numbers and functions that works exactly to a whole number answer. You must use all the numbers and functions once each and cannot repeat them. You will probably have to try different combinations before you find the method that works out exactly. Talk about what you are trying and why. You can use the number and functions in any order.

1. 46 5880 21 234 x + =

2. 18 35 7 23 + ÷ =

3. 16.52 1.9 2.6 3.4 – x =

4. 888 888 10 100 10 ÷ x ÷ =

5. 15.2 16 3.8 4 x ÷ =

Missing numbers. Find the missing number and explain how you did it. Be careful, they may be decimals. Try not to use a calculator.

6. ? x 15 = 57

7. 2.6 + ? x 12 = 7

8. 44 ÷ ? x 6 = 33

9. 16 + 9 ÷ ? = 2.5

10. ? x 27 ÷ 30 = 23.4

Estimate the answer, then work it out. Do not use the inverse method.

Explain how you estimated the answers.

11. 45 x ? = 1125

12. ? x 35 = 490

13. ? x 12 = 3120

14. ? x 15 = 72

15. ? x 9 = 74.7

16. 232 ÷ ? = 58

17. 2720 ÷ ? = 85

18. 156 ÷ ? = 12

19. 15.6 ÷ ? = 1.2

20. 7744 ÷ ? = 88
