Lesson Details

Key learning points

The whole has been divided (division bar).
The whole has been divided into __ equal parts (denominator).
One of the parts has been shaded (numerator).

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.
