6. Numicon Used for: Instant number recognition Bonds Ten bonds
Find the difference
Odds and evens
Addition
Subtraction

7. Numicon
In Year One we use Numicon to find the difference

8. Numicon Odds and Evens In Year One we learn to spot the odd one out.
In Year Two we develop our understanding to remember:
odd+odd=even
even+even=even
even+odd=odd

9. Numicon
Ten Bonds
In Year 2 we use our ten bonds for the beginning of hundred bonds. E.g. If we know 7+3=10, we know 70+30=100.

18. Addition TO TO Adding by Partitioning: E.g.: 72 + 23
Collect the ‘tens’ together
= 90
Then collect the ‘ones’ together
2 + 3 =5
Find the total =95
We would use a hundred square to support with adding

19. Addition 72 82 92 93 94 95 Adding on a number line: 72 + 23 =
Start at 72
Jump forward in ‘tens’ twice (23=20+3)
Then jump forward in ‘ones’ three times.
+10
+10 +3 72 82 92 93 94 95

20. We would use a hundred square to support with subtracting
Subtraction
Subtracting by Partitioning:
TO TO
E.g.: 72 – 21
Subtract the ‘tens’
= 50
Subtract the ‘ones’
2 - 1 =1
Find the total = 51
We would use a hundred square to support with subtracting

21. Subtraction 51 52 62 72 Subtracting on a Number Line: 72 – 21 =
Start at 72
Jump backwards in ‘tens’ twice (72-20=52)
Then jump backwards in ‘ones’. -1
-10
-10 51 52 62 72

22. Multiplication
Using objects or pictures: 3 lots of 5, 3 groups of 5, 3 x 5 = 15

23. Multiplication Multiplication as repeated addition: 5+5+5=15
3 x 5 = 15
Start at 0.
Jump 5 places on the number line 3 times and see what number you land on.

24. Divison Sharing into equal groups: 15 ÷ 3 = 5
There are 15 strawberries. There are 3 boxes. How many strawberries are in each box?

25. Division Division as repeated subtraction: 15 ÷5=3
Start at 15. We know it is a multiple of 5.
See how many times you can subtract 5 25

26. Multiplication and Division
Arrays:
3 x 5 = 15, 5 x 3 = 15, 15 ÷ 5 = 3, 15 ÷ 3 =5 5 3

28. National Curriculum Statutory Requirements
In Year One pupils should be taught to:
Count to and across 100, forwards and backwards, beginning with 0 or 1, or from any given number.
Read and write numbers from 1 to 20 in numerals and words.
In Year Two pupils should be taught to:
Count in steps of 2, 3, and 5 from 0, and in tens from any number, forward and backward.
Read and write numbers to at least 100 in numerals and in words.
