A unit fraction is a fraction that has a numerator of one.

The denominator is the number on the bottom of a fraction. It tells us how many parts the whole has been divided into.

Find the whole when the size of a unit fraction is known

Maths

In this unit pupils will find unit and non-unit fractions of whole numbers and explore parts and wholes. In the future unit pupils will use representations to describe and compare two fractions. They will  explain the relationship within families of equivalent fractions and use their knowledge of common equivalents to compare fractions with decimals.

In the prior unit pupils multiplied an improper fraction and a mixed number by a whole number. In this unit pupils will find unit and non-unit fractions of whole numbers and explore parts and wholes.
