1. Subtraction using number lines - PowerPoint 40-60 months
This powerpoint can be used to support the teaching of ‘Number’ targeted towards the month age band.

2. Teachers tip:
This can be used to support subtraction. Read the number sentence and refer to the number line. Emphasise which way we need to go (backwards=less). Now use the number line to solve the simple subtraction problems.
Why not make your own individual number lines and get the children to solve the problem alongside you.
