By doing one sheet a week followed up with one home learning almost identical has enabled the year 10 bottom set to retain some information and to actually try in test situations - rather than just putting anything down they actually think, Since doing these they have progressed onto answering '5' problem solving 1-9 questions and have stood at the front of the class and explained solutions - totally unthinkable at the start of the year.
