Identifying the number of equal or unequal parts in a whole
Lesson details
Learning outcome
I can identify the number of equal or unequal parts in a whole.
Key learning points
- The parts that make up a whole can be equal or unequal in size.
- The whole can be made of many parts, many parts can make the whole.
- We can describe the parts in the whole using the stem sentence: there are ___ equal/unequal parts in the whole.
Keywords
Equal - We say that two or more things are equal if they have the same quantity or value.
Unequal - We say that two or more things are unequal if they do not have the same quantity or value.
Common misconception
Sometimes parts can be deceptive and look equal but are in fact unequal. For example, a rhombus that has been split into parts with lines that are equally distributed.
Explore this further by presenting several examples like this if needed. You could ask the children to try and think of some examples where the parts look equal but are in fact unequal.
Teacher tip
This could be a practical lesson - get children to split shapes up and group them into equal and unequal parts. Many children will benefit from doing it instead of seeing it.
