Suitable for KS2, KS3 and Foundation KS4 Learning outcomes are: We can explain what a prime number is We can find all prime numbers up to 100 We can recall all prime numbers up to 19 We understand how prime numbers are used in cryptography This works well after my ‘Factors PowerPoint and Work Pack’ resource. The starter relies on pupils knowing about multiples and factors, as does showing if a number is prime. Please make sure to cover multiples and factors first.

Suitable for KS2, KS3 and foundation KS4. Covers factors, what they are, how to find factor pairs, and how to find and list common factors - a good lead in to a later lesson on HCF. Follows my ‘Multiples PowerPoint and Work pack’ lesson well. Pupils should know about multiples before doing the starting - if they don’t, don’t use the starter. Learning outcomes are: We can explain what a factor is We can find factors of numbers using times tables We can find factors of a number by finding factor pairs We can find common factors of numbers

Multiples Learning Sequence Suitable for KS2 KS3 and KS4, depending on ability (appropriate for low ability KS4) Animated PPT and associated work pack are both scaffolded fully. Outcomes are: We can explain what a multiple is We can find multiples of any number using multiplication We can easily identify multiples of 2, 3, 4, 5, 9 and 10
