Use a part-part-whole model to represent partitioning into more than two parts
Lesson details
Learning outcome
I can use a part-part-whole model to represent a whole partitioned into more than two parts.
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.
Teacher tip
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.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
