Notebook covering 2 to 3 lessons. Starting with introducing Factors, Multiples and Primes. Then Product of Primes, leading into using prime factor decomposition to obtain HCF and LCM of 2 numbers.
I provide in the notebook 2 ways of finding product of primes. First way (flower pot method) usually helps students remember, then once got the idea can do it the simple way.
Also provide the 4 point plan to finding the HCF/LCM. I did this with the students in a lesson so is not as neat as possible, but this is how I expect students to present answers to each question.
Works with high ability Year 7/8, up to low ability Year 11 GCSE students (worded questions at the end.)
