Year 6 Algebra Missing Number Problems

**A ready-to-teach Year 6 algebra lesson focused on solving missing number problems using reasoning and relationships between values in KS2 maths.

This lesson is fully standalone and ready to teach, supporting pupils in developing their understanding of unknowns, equations and logical problem solving.**

This Year 6 maths lesson focuses on algebraic reasoning through missing number problems involving two related equations.

Pupils are required to use logical thinking and arithmetic relationships to determine unknown values. They explore how changes in one value affect another and develop strategies for solving structured problems involving unknown quantities.

Teachers can use the included Smart Notebook input slides to model approaches clearly and guide pupils through step-by-step reasoning before independent work.

Pupils then complete a differentiated independent activity designed to support all learners while still providing appropriate challenge. The tasks develop confidence with algebraic thinking, problem solving and SATS-style reasoning questions.

This resource is ideal for Year 6 algebra lessons, KS2 reasoning practice, SATS revision, or targeted intervention sessions.
