In this unit pupils will compare and order unit fractions by looking at the denominator. In the future unit pupils will quantify the number of items in each part and connect to the unit fraction operator. They will calculate the value of a part by connecting knowledge of division and division facts with finding a fraction of a quantity.

In the prior unit pupils identified parts and wholes in different contexts. In this unit pupils will compare and order unit fractions by looking at the denominator.

In this unit pupils will compare and order unit fractions by looking at the denominator and understanding what it represents.
