  2. Each equal part is one-__ of the whole.

Common misconception

Children may not be used to a sorting diagram.

Show them some more simplified versions that they can understand easily (like the fruit and veg in the slides) before moving onto using their understanding of unit-fractions.

Keywords

  • Whole - The whole is all the parts or everything, the total amount.

  • Part - A part is some of the whole.

  • Equal/unequal - We say that two or more things are equal if they have the same quantity or value. We say that two or more things are unequal if they do not have the same quantity or value.

  • Fraction - A fraction describes the relationship between a part and a whole.

Whilst there are several suggested sorting diagrams in the slides, you may wish to encourage the children to start creating their own for one another to engage them and give them ownership of the learning.
