Great for differentiating: you can choose exactly what numbers you want your pupils to double and halve. I made this for my year 2s, but you could easily use for Year 1 as well.
It includes ladybirds so they can draw on the spots as a visual aid.
The wording is:
'Double ___ is ____
Half of ____ is ____.'
It should help the children to draw links between doubling and halving both verbally and visually.
