Students learn how to add fractions with different denominators using equivalent fraction diagrams. As learning progresses more able students are taught written methods.
The start of the lesson recaps finding equivalent fractions. In the main part students learn how to use equivalent fractions to add two more fractions together. Written methods are used to consolidate this approach. The plenary challenges students to explain the common misconceptions when adding fractions.
Differentiated Learning Objectives
- All students should be able to calculate the sum of two fractions with a common denominator.
- Most students should be able to use visual methods to find the sum of two fractions with different denominators.
- Some students should be able to use written methods to find the sum of two fractions with different denominators.
