Lesson details
Key learning points
- Objects can be divided into equal groups, sometimes with a remainder.
- Multiplication facts can be used to solve grouping problems.
- Multiplication and addition can show when a set of objects has been divided into equal groups with a remainder.
Common misconception
When writing equations to represent part-part-whole models, children may have difficulty recording the number of groups (as this numeral is not written in the model) and revert to repeated addition.
Encourage children to articulate their thinking as they record, e.g. there are ___ groups of ___ and a remainder of ___
