Teach solving equations and rearranging formulae step by step with this KS3 maths workbook. Includes 20 worked examples, structured practice and full teacher answers.
Balance models, bar models and inverse-operation diagrams help pupils understand each method before working independently.
Topics covered:
- Equality, unknowns, inverse operations and checking solutions by substitution.
- One-step and two-step equations, negative coefficients and unknowns on both sides.
- Equations involving brackets, fractions and decimals.
- Forming equations from word problems and geometry.
- Substituting into formulae and changing the subject, including brackets and fractions.
- Clearly marked optional extension: identities, equations with no solution, and rearrangements where the subject appears twice.
Teaching and practice:
- Diagnostic questions, clear rules and numbered worked steps.
- Guided and independent practice with dotted answer spaces.
- Mixed practice, error correction and delayed retrieval.
- Two 20-mark final checks.
- Full answers, marking guidance and teaching notes.
