I have been creating revision homework sheets by lookng through the specification and writing a question for each part. The students have found it very usefull to complete the questions then I give them a couple of topics to go over.
These sheets are specificaly for the New Edexcel GCSE modular syllabus. They include and objective for each question.
Please take a look at my blog:
A good set of questions based on the topics of factors, multiples, primes, HCF and LCM. Ideal as a homework sheet after teaching this lesson, a worksheet during a lesson or as a revision resource for pupils sitting an exam.
