UKS2 (Year 5 and Year 6) adding fractions with same and different denominators

Learning Objectives

Starter:

• To compare and order fractions

Main Lesson:

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


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


• To use the 4 operations applied to proper and improper fractions all both positive and negative (KS3)

This lesson consists of:

A Starter consisting of a series of progressively harder pairs of fractions which recaps comparing two or more fractions. A connect activity challenging children to identify and discuss methods that they might use to add two fractions – allowing you to assess prior learning.

An Interactive Whiteboard teaching introduction for both Notebook and ActivInspire flipchart, to teach children to understanding how to add fractions 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 add fractions.

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