Lesson details
Key learning points
- When constructing a whole, you can start with the part.
- To construct a whole, you need to know how many parts make it up and whether those parts are equal.
- The whole can be one shape or a group of objects
- Different shaped wholes can be constructed using the same shaped equal parts.
Keywords
Whole - The whole is all the parts or everything, the total amount.
Part - A part is some, but not all, of the whole.
Construct - Constructing something involves making something by joining parts together.
Common misconception
Children may not include the original part when constructing a whole. E.g. if the given part is one of four equal parts of the whole, they may construct five parts together in total.
How many parts does your whole have?
