About this resource Algebra Before Algebra is designed for pupils who become confused when letters first appear in maths. Rather than jumping straight into memorised methods, the pack explains what algebraic letters actually mean, why a number beside a letter represents multiplication, how an expression differs from an equation, and how to replace variables with given values. Clear explanations, visual models, worked examples and carefully sequenced questions help pupils build genuine understanding before moving on to more advanced KS3 algebra.
