UKS 2 (Year 5 and Year 6) subtracting fractions, improper fractions and mixed numbers

Learning Objectives

Starter:

• To compare and order fractions

Main Lesson:

• To subtract fractions with the same denominator, and denominators that are multiples of the same number (Year 5)


• To subtract fractions with different denominators, using the concept of equivalent fractions (Year 6)


• To use the 4 operations applied to proper and improper fractions(KS3)

This lesson consists of:

A Starter consisting of a series of progressively harder problems where the children have to compare mixed numbers with improper fractions and use <> sign to show which are larger. A connect activity challenging children to identify and explain the nature of common errors when subtracting fractions.

An Interactive Whiteboard teaching introduction for both Notebook and ActivInspire flipchart, to teach children to understanding how to subtract fractions, improper fractions and mixed numbers with common denominators, with denominators where one is a multiple of the other and where two fractions have different denominators, and changing fractions to have the same denominator in order to add these fractions.

A 4-way differentiated series of tasks requiring children to subtract fractions. Answers included to ease marking

A final AFL / Next Steps task, asking children to work out what final step has been missed off by a fictional student Sam.
