Use a part-part-whole model to represent partitioning into more than two parts
I can use a part-part-whole model to represent a whole partitioned into more than two parts.
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.
Keywords
Whole - All of something. Complete.
Part - A piece of a whole.
Partition - To break up a whole into parts.
Part-part-whole model - A pictorial representation that shows the whole and its parts.
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-part-whole model in different orientations.
Use a variety of part-part-whole models with different numbers of parts and in different orientations for children to practise partitioning and combining numbers. You can make part-part-whole models from paper plates joined with pieces of string.
