Teach KS3 linear graphs step by step with 20 worked examples, clear coordinate grids and progressive practice. Pupils plot straight-line graphs from tables, calculate gradients, identify x- and y-intercepts and write equations in the form y = mx + c.

• Covers positive, negative, zero and fractional gradients, direct proportion, intersections, and cost and distance–time graphs.
• Includes diagnostic questions, error correction, two 20-mark assessments and retrieval practice.
• Comes with a 92-page student workbook and a 45-page teacher guide with full answers, model graphs and mark schemes. Both are supplied as PDFs and editable Word files.
