A complete Year 7 Core maths PowerPoint lesson on substituting values into expressions containing one operation.

This classroom-ready resource follows a carefully sequenced I Do–We Do–You Do structure, moving pupils from vocabulary and representation through explicit modelling, guided practice, assessment for learning and independent application.

Included:
• six-question retrieval starter with answers
• pupil-friendly key vocabulary and concept representation
• three matched I Do–We Do examples with modelling space and completed solutions
• 12 single-question mini-whiteboard checks with immediate answers
• 24-question minimally different practice task using controlled variation
• Developing, Secure, Greater Depth and substantial Super Challenge tasks
• one-slide shared answers for all routine tiers
• misconception diagnosis and correction
• problem solving, reasoning with constraints and exam-style questions
• exit check with answers

The lesson is designed for whole-class display: no worksheets or printing are required. Every question and answer has been checked for mathematical accuracy, wording, progression and classroom readability. Essential pupil-facing text is at least 24 pt, question numbering is consistent, and negative substitutions use clear bracket notation.

Ideal for KS3 maths lessons, cover work, intervention, revision or departmental curriculum planning.
