2. Purpose of workshop To explain how we teach your child x and ÷ in KS1.
To give you some ideas of how you can help and support your child at home.

3. Maths – when do we use it?

4. Multiplication vocabularyx

5. Multiplication
Counting in 10s

6. Multiplication
Counting in 2s

7. Multiplication
Counting in 5s

8. Multiplication
Children need to learn multiplication tables and multiplication facts.
Yes – learn to recite tables but also need to know table facts at random.
e.g. 8 lots of ten are?
And answer questions like “ How many tens in 80?”
Not secure in times tables until able to do this quickly.
Should be working on 10x, 2x and 5x tables in Year 1, continue and work on 3x and 4x in Year 2.

9. Multiplication Repeated addition 10 + 10 + 10 + 10 = 40
Problem solving
There are 10 pencils in a pack.
How many pencils are there in 4 packs?
Repeated addition
= 40

10. Multiplication
3 times 5 is the same as = 15 or 3 lots of 5 or 3 x 5
On a number line 5 5 5 5 10 15

11. Multiplication
As an array
3 x 5 = 15
5 x 3 = 15

12. Problem solving
There are 15 apples in a tray. Ling has 4 trays of apples.
How many apples does Ling have altogether? Show how you work it out.
Ella’s dad washes some cars. He uses 12 buckets of water. Each bucket has 5 litres of water. How many litres of water does he use altogether?
Your turn! Can you draw pictures or make jottings to show how you could
work one or both of these out?

13. Ella’s dad washes some cars. He uses 12 buckets of water
Ella’s dad washes some cars. He uses 12 buckets of water. Each bucket has 5 litres of water. How many litres of water does he use altogether?
Or = 60
Or count in 5s 12 times. Or 12 x 5 =60

14. There are 15 apples in a tray. Ling has 4 trays of apples.
How many apples does Ling have altogether? Show how you work it out.

15. Division vocabulary share equally divide divided by groups halve half

16. Division
Children start by understanding equal groups and sharing items out in play and problem solving. Count in 2s, 10s and 5s.
Sharing equally. There are 6 sweets. How many sweets can 3 children have each?

17. Grouping There are 6 sweets. How many children can have 2 each?
Division

18. 2 4 6 8 10 12 14 16 Count in 2s until you get to 16.
So how can you work out a division sum using times tables?
Count in 2s until you get to 16.

19. Division using an empty number line
How many groups of 5 are there in 25?
25 ÷ 5 = 5

20. Your turn! 6 groups of 5 make 30. So 6 teams.
There are 30 children in the class. They need to be in teams of 5. How many teams will there be? Use an empty number line to work it out.
6 groups of 5 make So 6 teams.

21. How you can support your child at home
