Learning Objectives

Starter:

• To convert between mixed numbers and improper fractions

Main Lesson:

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


• 
  
• 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 conversion problems involving improper fractions and mixed numbers. A connect activity challenging children to identify the kind of errors that can be made when adding improper fractions and mixed numbers – allowing you to correct misunderstandings and assess prior learning. .

An Interactive Whiteboard teaching introduction for both Notebook and ActivInspire flipchart, to teach children to understanding how to add improper 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. The introduction also teaches children to convert from mixed numbers to improper fractions before carrying out any calculations

A 4-way differentiated series of tasks requiring children to add improper fractions and mixed numbers.

A final AFL / Next Steps task, asking children to apply their understanding of the addition of fractions to subtracting fractions.
