Why this why now
This unit builds on solving linear equations from year 7 where pupils learnt to rearrange aan equation to find a specific value that satisfied the equation. In expressions and formulae, pupils use their understanding of rearrangement to change the subject of a formula. Pupils are then introduced binomial equations in preparation for trigonometry.
Prior knowledge requirements
- Simplify algebraic expressions
- Use substitution in expressions and formulas
- Rearrange formulas involving one or more steps
