KS3 Algebra
Algebra is where KS3 maths starts to feel powerful — using letters to describe patterns, solve problems and draw graphs. This strand covers simplifying expressions, solving equations, sequences and straight-line graphs, with a video, worksheet and test paper for each.
Topics in Algebra
Expressions & Simplifying
Collecting like terms, multiplying and dividing terms, expanding single and double brackets, factorising, and substituting into expressions and formulae — the core KS3 skills for working with algebra. Includes an exam-style expressions test paper with a full mark scheme.
Solving Equations
Solving one- and two-step equations, equations with brackets and with unknowns on both sides, and forming and solving equations from a context — one of the most important KS3 algebra skills. Includes a full solving-equations test paper with a worked mark scheme.
Sequences
Term-to-term and position-to-term rules, finding and using the nth term of a linear sequence, and recognising special sequences — the KS3 patterns that lead into GCSE algebra. Includes a full sequences test paper with mark scheme.
Graphs & Coordinates
Coordinates in all four quadrants, midpoints, plotting straight-line graphs, y = mx + c, and reading conversion and distance–time graphs — the KS3 graph skills that connect algebra and geometry. Includes an exam-style graphs and coordinates test paper with mark scheme.
