A complete Year 3/4 maths enterprise project where pupils plan a mini business with a £10 budget. Full lesson plan, two differentiated worksheets, price list and certificate included.
This £10 Mini Business Challenge is a fully resourced, ready-to-teach maths and enterprise lesson for Year 3 and Year 4 (ages 7-9). Pupils work in pairs to invent a small business, plan their costs within a £10 budget, decide a selling price and calculate their predicted profit. The lesson culminates in pairs pitching to an AI “judge” (a copy-paste prompt is included for Claude or ChatGPT) who scores their maths, creativity and realism.

Teacher’s lesson plan with timings, learning objectives, differentiation for SEND/EAL/stretch, assessment guidance and an AI judge prompt
Worksheet A - scaffolded version with a £10 wallet, part-filled cost table and sentence-starter profit calculator
Worksheet B - open-ended stretch version with five extension challenges and a self-check rubric
