Lesson details
Key learning points
- A whole group can be split into more than 2 parts and the parts may look different.
- Make up a story that represents partitioning into three or more parts.
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.
Common misconception
Children may get confused between the parts and the whole.
Ask the children 'What does this number represent?' and encourage them to use the stem sentences to justify their answers.
Use a variety of real life stories to go with the partitioning examples. Encourage children to make up their own stories to embed the learning.
