Students learn how to change the subject of a formula by factorising and the balance method.
A treasure hunt activity is included as an additional resource for extra practice and consolidation.
Differentiated Learning Objectives
- All students should be able to rearrange a formula in the form ax+bx=c by factorising to make x the subject.
- Most students should be able to rearrange a formula in the form (a/x)+b=c to make x the subject
- Some students should be able to rearrange a formula in the form a/(x+d) = b/(x-c) to make x the subject.
