This week we are spelling common exception words:

Please also learn the addition and subtraction bonds to 20 (fact families). This is a step on from last week's number bonds to ten.
e.g.
16+4=20 4+16=20
20-16=4 20-4=16
Using a bar model can also help us to visualise these facts
E.G.
20 | |
2 | 18 |
18+2=20
2+18=20
20-18=2
20-2=18
