Lesson details

Key learning points

Draw attention to the fact that each part is smaller than the whole.
Partition objects into 3 parts in as many ways as possible.

Common misconception

Children may not realise that a whole can be split in different ways and into more than two parts.

Provide lots of practical partitioning and recombining of objects and record on a part-whole model in different orientations.

Keywords

Whole - All of something. Complete.
Part - A piece of a whole.
Partition - To break up a whole into parts.
Part-whole model - A pictorial representation that shows the whole and its parts.

Use a variety of laminated part-whole models with different numbers of parts and in different orientations for children to practise partitioning and combining numbers. Make part-whole models from paper plates joined with pieces of string.
