1. Parent Workshop Mathematics

2. Aims: - To demonstrate how we teach Mathematics in Reception to Year 2 - To allow time for you to play with some of the resources we use - Give you some ideas of games/resources you can play with at home

3. Addition +

4. Reception ~ Using quantities & objects add two single-digit numbers
~ Count on back to find an answer

5. Using numicon demonstrate how you would solve the following question;
Year 1
~ Addition with numbers up to 20
5 + 3 =
Using numicon demonstrate how you would solve the following question;
7+4 =
Focus on counting to 20 in yr1 although ch. Need to work with numbers up to 100 by the end of the yr.
Pratically – moving the objects and being able to count on – 3 ….4, 5 etc
Finding number bonds to a number – can you make number bonds to 8 using the nuimcon
Using numicon to add simple additions – discuss bridging the 10
Numberline – counting on

6. Using base 10 demonstrate how you would solve the following question;
Year 2
~ Addition with two digit numbers =
Using base 10 demonstrate how you would solve the following question; =
By counting on a ten and adding a one

7. Year 2 34 + 13 = ~ Addition with two digit numbers
Add by partitioning on a blank number line….
Practise 10 more lots before we move on to partitioning numbers
Show on board

8. Year 2
~ Addition with two digit numbers using column addition =
T O 4
2 7 +
Better as only adding 1 digit essentially
- understanding needs to be secure of tens and ones
Carrying the 10

9. Subtraction -

10. Reception
~ Using quantities & objects subtract two single-digit numbers
~ Count back to find an answer

Real objects
1 less

11. Using numicon demonstrate how you would solve the following question;
Year 1
~ Subtraction with numbers up to 20
Using numicon demonstrate how you would solve the following question;
8-3 =
Numicon – how we use it – show on board
Using concrete resources
Taking physical resources away
13 – 5 =

12. Year 2 34 - 11 = ~ Subtraction with two digit numbers
By taking a ten away and taking a one away

13. Year 2 34 - 13 = ~ Subtraction with two digit numbers
Subtract by partitioning on a blank number line….
Practise 10 more lots before we move on to partitioning numbers
Show on board

14. Year 2
~Subtraction with two digit numbers using column subtraction =
T O 4
2 7 -
Better as only adding 1 digit essentially
- understanding needs to be secure of tens and ones
Carrying the 10

15. Multiplication x

16. Reception ~ Solve problems involving doubling
~ Solve practical problems involve combining groups of 2, 5 or 10
Numicon picture

17. Using numicon demonstrate how you would solve the following question;
Year 1
~ Multiply using concrete objects, pictorial representations and arrays with the support of the teacher =
Using numicon demonstrate how you would solve the following question; =
Massive focus on doubles and halves and children need to be able to count in 2’s, 5’s and 10’s
Doubles + = 4

18. Using numicon demonstrate how you would solve the following question;
Year 2
~ Multiply using arrays and repeated addition (2’s, 5’s & 10’s)
Repeated addition – using concrete apparatus, numicon, on a number line & a bead bar
Using numicon demonstrate how you would solve the following question;
5 x 3 =
Commutativity - array
5 times 3 ~ = lots of 5 ~ 3 x 5
5 x 3 is the same as 3 x 5

19. Division ÷

20. Reception ~ Solve problems including halving & sharing
~ Solve practical problems that involve sharing groups of 2, 5, 10 into equal groups

Practical object picture

21. Using objects demonstrate how you would solve the following question;
Year 1
~ Grouping & sharing in small quantities
6 ÷ 2 =
Using objects demonstrate how you would solve the following question;
8 ÷ 2 =
Equal groups
Sharing items during play & problem solving
Show numicon – placing tiles of 2 on a 6 tile
Number line - show
Numicon
Repeated subtraction on number line

22. Solve this problem on a number line: Share 8 sweets between 2 people.
Year 2
~ Calculate mathematical statements for division & write them using division (÷) and equals (=)
Sharing equally – children will develop their own ways of jotting
Repeated subtraction – using a number line
Solve this problem on a number line:
Share 8 sweets between 2 people.
5 times 3 ~ = lots of 5 ~ 3 x 5
