Highest Common Factor / Lowest Common Multiple
Just an update, really. Someone contacted me about my HCF and LCM lessons being linked wrongly on here, and I realised that they were a bit crap, so I tidied them up.
I removed a lot of ‘narration’ (I initially put these in to help teachers who just wanted to pick up and go, but it made the lessons too click-y, I always skipped them) and put in example problem pairs. I also added a whole lot of questions. For instance:
I noticed that these type of questions come up a lot in exams so I thought I should add them into my lessons.
There’s also a whole lot of worded questions now.
There’s three lessons in one here, really. HCF, LCM and HCF mixed, worded questions.
Think this is a lot closer to being comprehensive.
