do. 8 + 4 =

8

8 + 4 = 12

10 11 129

+1 +1+1 +1

Chunking

1. Draw the line. 2. Biggest number at the beginning. 3. Partition the second number. 4. Add on the tens.5. Add on the units. 5. Find the answer.

13 + 12 = 25 10 2

13

+ 10 + 2

23 25

Partitioning 1. Partition both numbers.2. Add the tens together.3. Add the units together. 4. Add the 2 numbers together.

14 + 11 = 25

10 4

10 + 10 = 20

Partitioning the second number

1. Partition the second number. 2. Subtract the tens. 3. Subtract the units.4. Find the answer

26 – 14 = 12

10 4

26 – 10 = 16

16 – 4 = 12

DivisionEggs in baskets

12 ÷ 3 = 4

1.Draw 3 baskets (the second number shows how many baskets to draw.

2.Share the first number into the baskets.

3.Count 1 basket.

Finally...•Practise is the key to retaining these methods.

•Children should also practise these in real situations.

•Keep it short, snappy and fun!!
