KS2 (Years 3–6) · Mathematics
Algebra Introduction
What is it
Introductory algebra at KS2 means using letters or symbols to represent unknown numbers in simple expressions and equations, and finding missing numbers in number sequences and simple formulae.
Why it matters
This is a child's first taste of the abstract thinking that dominates GCSE and A-Level maths — starting gently now, with concrete examples, prevents algebra feeling like an alien topic when it's introduced formally at KS3.
Exam tip
Frame early algebra as a 'missing number puzzle' rather than using the word 'algebra' too heavily at first — it keeps the topic feeling approachable rather than intimidating.
