Identify 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
- Parts can be equal or unequal in size.
- There are __ equal parts in the whole.
- There are __ unequal parts in the whole.
Keywords
Whole - The whole is all the parts or everything, the total amount.
Part - A part is some of the whole.
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, the 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. Getting the children thinking of this will boost understanding.
Teacher tip
The characters in the slides demonstrate a number of different contexts and practical tasks. Instead of following them, you could do these with the children instead. Get them split shapes up and group them into equal and unequal parts. Many children will benefit from doing it instead of seeing it.
