Number Target Challenge Level 17 increases the level of constraint introduced in Level 16. Pupils are less likely to find a solution through straightforward operation choices and must search for less immediate connections between the supplied numbers. Many puzzles require a carefully created intermediate result. This might involve using one large number to modify another or constructing a factor that is not obvious from the original selection. The resource includes: 20 solver-verified expert puzzles Timer-enabled PowerPoint Standard macro-free PPTX Printable PDF version Consistent classroom-ready presentation Increasing strategic demand This level is suitable for high-attaining KS3 and KS4 pupils, maths clubs, enrichment programmes, competitions and extension lessons. The puzzles develop persistence, flexible thinking and the ability to organise complex calculations. Pupils can work independently before comparing approaches with a partner or group. A useful follow-up is to ask pupils which available number was hardest to use effectively, or which intermediate value made the solution possible. Level 17 is part of the expert section of the complete 20-level progression, leading towards puzzles with extremely limited and highly sophisticated solution routes.\u003c\/p\u003e\u003ch3\u003eYour download\u003c\/h3\u003e\u003cp\u003e1 level, containing 20 puzzles.
