1. Supporting Primary Maths at Home: Subtraction
Outline of the workshop-
Being Maths Role Models
The process of learning subtraction skills
Key skills you need to practise at home
Supporting Using and applying subtraction at home

2. What’s the most important message for our children?
Our brains are trainable muscles- with practise we can succeed.
Persistence and confidence are key to learning in maths.
Maths is a passport to later life...
What to do if stuck?

3. Subtraction Stage 1 Practical activities and discussion
Finding one less than a number from 1 to 10 (then up to 20)
Begin to relate subtraction to “taking away”
Begin to make links with vocabulary (less, count back, subtract, take away, difference)

4. Subtraction Stage 2 Count back from a given number to solve problems
Begin to use the - and = sign to record mental calculations
Know by heart all subtraction facts to 10 (then 20)

5. Subtraction Stage 3 Using informal pencil and paper methods (jottings)
Use a number line to record complimentary addition
84 – 56
=28

6. Subtraction Stage 4
Securing an understanding of the place value of digits
Subtracting tens and units as simple taking away but with a secure understanding (then hundreds)
34- 13= is......
30- 10= = = 21

7. Your turn... =

8. Subtraction Stage 4 563 - 248 500 + 60 + 3 - 200 + 40 + 8

9. Subtraction Stage 4 Cont……. 500 + 60 + 3 - 200 + 40 + 8

10. Subtraction Stage 5
Decomposition extended to decimals and larger numbers
Contracted recording at decomposition
6476
-2684
3792

11. Subtraction Stage 6 Consolidation of stage 5
Contracted recording of decimals

12. Key elements to practise at home.... Practise is key!
Number recognition
(Bingo for any numbers, recognising door /car registration numbers/ knowing the date, using coins )
Counting
(When shopping, estimating amounts, using coins,
Counting on and back e.g. How many steps to the sea...can we count back...)
No. bonds to 10, 20
(Make own puzzles, flash cards, linking number toys)
Times tables-
This can be practised anywhere at any time!
If you aren’t secure- practise with them!
Measurement
Distances, amounts- capacity in practical and purposeful contexts- basic recognition of amounts! Comparing which has more/less
Time
Basic time telling but also planning a journey- read the time tables, work out estimated times of arrival
