Designed to support students mastering KS3 Mathematics and Functional Skills Level 2, this comprehensive resource focuses on the practical application of percentage increase, decrease, and compound change within the engaging context of a professional car dealership. By using high-interest scenarios—such as luxury car discounts, VAT surcharges, and asset depreciation—students move beyond abstract theory into concrete, real-world financial literacy.

This unit of work is meticulously structured to provide a low-threshold, high-ceiling learning experience. It begins with “Rapid Mechanic” mental math warm-ups to build fluency, progresses through tiered “Showroom” challenges (Bronze, Silver, Gold), and culminates in “Diamond Level” tasks involving multi-step compound depreciation and reverse percentage VAT calculations. The inclusion of detailed step-by-step walkthroughs and a master answer key makes it ideal for both first-time teaching and independent revision.
