Number Target Challenge Level 7: Intermediate Builder | 20 Number Puzzles

20 intermediate arithmetic puzzles requiring stronger number grouping, operation choice and multi-step planning. Includes PowerPoint, PPTX and PDF. Number Target Challenge Level 7 develops the intermediate skills introduced in Level 6. Pupils must make better use of number relationships and consider how one calculation will affect the choices available later in the solution. The target may be approachable in several ways, but inefficient early decisions can quickly make the puzzle harder. This gives pupils a meaningful reason to pause, estimate and plan. The resource contains: 20 solver-verified puzzles Timer-enabled classroom PowerPoint Standard macro-free PPTX version Printable PDF for written solutions Gradually increasing difficulty Flexible use for individuals, pairs or teams Level 7 is ideal for KS3 lesson starters, fluency practice, extension work, intervention, homework, cover lessons or extracurricular maths sessions. The puzzles promote arithmetic fluency without presenting calculations as isolated exercises. Pupils practise addition, subtraction, multiplication and division within a clear problem-solving purpose. Further challenge can be added by requiring every available number to be used, restricting an operation, setting a time limit or asking pupils to prove that their route is efficient. This level forms part of the intermediate section of a 20-level progression leading towards increasingly constrained and sophisticated number problems.
