Overview:
BREAKING THE ICE
Welcome your students with a thrilling challenge that feels more like a spy mission than a maths lesson. Crack the Code is a dynamic, team-based or individual game where students race to decipher hidden messages using mathematical skills rather than prior knowledge. They won’t realise they’re practicing key GCSE skills until they are told.

Why It Works
• Differentiation Built-In:
Each code level is tiered to support all learners—from those needing scaffolding to those ready for stretch and challenge. Hints, bonus clues, and optional “intel packs” allow for tailored support without compromising engagement.
• Assessment Objectives Embedded:
• AO1 (Use and Apply): Students substitute values, collect data, and perform calculations to unlock clues.
• AO2 (Reason and Interpret): They analyse patterns, spot errors, and justify their decoding strategies.
• AO3 (Problem-Solve): Strategic thinking is key—students must decide which clues to tackle first, how to collaborate, and how to manage time.
• Topics Covered Without Realising:
• Substitution into expressions
• Data collection and analysis
• Percentages and proportional reasoning
• Logical deduction and strategic problem-solving
• Teacher-Controlled Duration:
