Key learning points

Common misconception

Children will often think that the denominator is just how many parts a whole has been divided into and forget that the parts must be equal.

If some children are struggling with this then get them to spot examples and non-examples drawn quickly on whiteboards. You can also make connections with sharing food with siblings/friends fairly. Some might endure 'one cuts, one chooses' at home.
