Number Target Challenge Level 14: Advanced Challenge | 20 Maths Puzzles

20 constrained advanced puzzles requiring strong arithmetic reasoning, accurate use of large intermediate values and careful forward planning. Number Target Challenge Level 14 is intended for pupils who are ready for sustained arithmetic problem-solving. Targets are more difficult to approach directly, and solutions often depend on identifying an important intermediate value several steps before reaching the answer. Pupils must balance ambitious calculations with control. Creating a large product may appear helpful, but it is only useful when there is a realistic way to adjust it to the exact target. The resource contains: 20 advanced challenge puzzles Timer-enabled classroom PowerPoint Macro-free PPTX alternative Printable PDF version Solver-verified targets Progressive strategic demand Level 14 can support KS3 or KS4 enrichment, high-attaining groups, maths-club sessions, competitions, revision and extension activities. It promotes perseverance because pupils may need to abandon an unproductive route and begin again with a different structure. This provides a useful context for discussing systematic trial, checking and learning from unsuccessful attempts. Pupils can be challenged to explain the decisive step in their solution or demonstrate why a seemingly promising approach cannot work. This is the penultimate advanced level before pupils progress to advanced mastery and then the expert phase.
