Teach multiplying and dividing with negative numbers through a complete, classroom-ready Year 7 Core PowerPoint lesson.

This carefully sequenced resource develops more than a memorised sign rule. Pupils use multiplication patterns and inverse fact families to understand why different signs produce a negative result and matching signs produce a positive result.

The lesson includes:

• six-question retrieval starter with answers;
• precise vocabulary for factor, product, quotient, sign, magnitude and inverse;
• visual sign-pattern representation and concept model;
• three matched I Do–We Do examples;
• exactly 12 mini-whiteboard diagnostic checks, each followed immediately by its answer;
• 24 minimally different questions using controlled variation;
• Developing, Secure, Greater Depth and Super Challenge practice;
• misconception analysis and correction;
• contextual problem solving and systematic reasoning;
• exam-style questions with mark guidance;
• exit check and complete answers.

Questions are deliberately varied to expose common misconceptions, including treating any negative sign as making the answer negative, mishandling division with two negative numbers and confusing magnitude with sign. Greater Depth tasks require comparison, reverse reasoning, examples, constraints and justification rather than simply using larger numbers.

The PowerPoint is fully editable, print-free and designed for whole-class display. All pupil-facing questions use clear bracketed numbering, compact headers and large classroom-readable text.
