1. Thornford School Mathematics Parents workshop
How to help your child

2. Mathematics
Maths is a proficiency which involves confidence and competence with numbers and measures.
To take part in tomorrow’s world you will need maths:
when our Year 6 children are of working age, 80% of them will be using technology that has not been invented yet

3. New Primary Strategy Counting, partitioning and calculating
Securing number facts, understanding shape
Handling data and measures
Calculating, measuring and understanding shape
Securing number facts, relationships and calculating

4. Mathematics at Thornford
Consistent approach to mathematics to support all pupils
Daily maths lesson
Cross-curricular lessons
Dedicated events
Skills are consolidated
High expectations

5. Daily maths lesson
Mental oral starter
Main teaching
Plenary

6. Differentiation Daily maths lesson High achievers will have extension
Springboard: support to achieve their potential
SEN: extra breadth of experience and consolidation of basic concepts

7. Teaching
Mental calculations and number facts must be established before standard written methods are introduced
Children learn a way of thinking and they can be quickly prompted into these ways of thinking with open questions.
Everyone can use mental methods if they can find numbers they are comfortable with

8. Questions
“Can you see numbers close to these that would be easier to deal with?”
“Would it be easier the other way round?”
“Could you break it up and work on the bits separately?”
“Could you use doubles or halves?”
“Would it help to jot down a number half way?”
“Would it help to use a number line?”

9. School calculations booklet
In the booklet, it explains all the methods of calculation: addition, subtraction, multiplication and division, which we use at school.

10. Ways to help your child
Mental calculations first before standard written methods
Let your child explain their method to you
Don’t do too much at once
Start from where your child is
Let them make mistakes and know this is acceptable
Be positive and enthusiastic

11. Addition in Reception
add 1 more
add 2 more

12. Addition in Year 1 and 2 – lots of methods!
Put the number in your head, and then count on using your fingers
Use a ‘numbered’ number line to ‘hop’ on the amount to be added (moving onto using an ‘empty’ number line)
Use the 100 number square to help – left, right 1 square to add/subtract 1, up, down 1 square to add/subtract 10 etc
Learn number bonds to 10 (and 20). Use as a basis for working out other facts, e.g = 10, = 100
Partition (split up) a number into tens/units to help
We use a variety of methods & vocabulary , e.g. Count on, add, plus etc. and most importantly encourage the children to use the method they feel most comfortable with!

13. Addition in Year 3 and 4

14. Using number lines in Addition and Subtraction

15. Adding numbers using the number line.25 47
So how do we do this using the number line?

16. We use the strategy called: Counting On
You need to think about:
What number shall I start with on my number line?
What number do we want to count up by?
Are there any number bonds that can help me?

17. 25 + 47 = Use the counting up method!! 47 67 70 72
+20 +3 +2 47 67 70 72
So we start at the biggest number…47
And count up 25 places
What number do we end on???
So…. = 72

18. Addition in Upper Key Stage 247
+ 76
110 (40+70)
(7+6)
123

19. Addition in Year 5 and 6 47
+ 76
123 1

20. Grid method multiplication of 23 X 820 3 8

21. Grid method multiplication of 23 X 820 3 8
160

22. Grid method multiplication of 23 X 820 3 8
160 24

23. Grid method multiplication of 23 X 820 3 8
160 24
184

24. Chunking for division 96 divided by 6
How many 6s in 96 ?
Instead of ……..
We take away a multiple of 6 we know eg
60 (this is 6x10 and is less than 96 ) 96
36 we have 36 left over which we know is 6x6

25. repeated subtraction of multiples of 696
- 60 (10 X 6) 36
- 36 (6 X 6)
So we can take away 16 lots of 6 from 96
So 96 divided by 6 = 16
