Get the most out of your KS3 Maths Knowledge Organiser (Higher Level) (9781789088588) with this marvellous matching Knowledge Retriever (9781789088601)! Here's how it works: once you've learnt a topic from the Knowledge Organiser, find the first matching page in this Knowledge Retriever (the 'First Go') and test your memory by filling in as much info as you can. Wait a bit, then try the 'Second Go' - this one's a bit trickier, to really make sure everything has sunk in. When you think you know your stuff, put it to the test with the mixed practice quizzes!
