Solve problems using part-part-whole models with more than two parts
Lesson details
Learning outcome
I can solve problems using a part-part-whole model to represent a whole partitioned into more than two parts.
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.
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.
Teacher tip
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 and to represent them on part-part-whole models with more than two parts, saying what each numner represents.
