Identifying equal parts in a whole in different contexts

I can identify the number of equal or unequal parts in a whole in different contexts.

Lesson details

Key learning points

  1. A non-unit fraction labels more than one out of the number of equal parts in the whole.
  2. A fraction is made from equal parts of the whole.
  3. Parts can be different shapes and still be the same size.
  4. When counting different objects that make a whole, the objects can be of unequal size.

Common misconception

Pupils may find the concept of different shapes (and sizes, for number of objects) a little confusing.

Show pupils images where parts are different shapes (area fractions - parts of a whole shape) but can easily be seen to be the same size.

Keywords

  • Equal - Equal means exactly the same amount or value.

  • Unequal - Unequal means not exactly the same amount or value.

In this lesson, pupils will look at equal and unequal parts of a whole. Pupils will have experience of differentiating between finding the fraction of the area of a shape and the fractions of a number of objects.
