Addition Number lines
1. First number shows where to start.2. Second number shows how many jumps to
do. 8 + 4 =
Empty number lines 1. Draw the line. 2. First number at the beginning. 3. Second number is the amount of jumps. 4. Fill in the numbers5. Find the answer.
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
10 1
4 + 1 = 5
20 + 5 = 25

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!!
