Students learn how to subtract fractions with using equivalent fraction diagrams. As learning progresses more able students are taught written methods.The start of the lesson recaps addition with fractions. In the main part students learn how to use equivalent fractions to find the difference between two fractions. Written methods are used to consolidate this approach. The plenary challenges students to combine addition and subtraction by finding the missing values in a number pyramid.
Differentiated Learning Objectives
- All students should be able to calculate the difference between two fractions with the same denominator.
- Most students should be able to use visual methods to find the difference between two fractions.
- Some students should be able to use written methods to find the difference between fractions and mixed numbers.
