Let your children experiment with prime numbers in this Year 5 Prime Numbers Discussion problem, where two in-depth and open-ended questions allow children to think deeper about primes. An answer page with example answers is included to ease your marking, but it also gives children another opportunity to think about the way they got to their answer, and consider alternative routes and methods.

Use after our Modelling PPT, Varied Fluency and Reasoning and Problem Solving worksheets to ensure your children have a good understanding of primes before moving on to this trickier task.
