Maths

Find a unit fraction of a quantity using representations

Explain how dividing by a whole number relates to multiplying by a unit fraction

Use knowledge of multiplying a whole number by a unit fraction to solve problems

Find a non-unit fraction of a quantity using mental and written calculation strategies

Multiply a whole number by a proper fraction

Explain when a calculation represents scaling down and when it represents repeated addition

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

Find a unit fraction when the size of a non-unit fraction is known

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.
