I have put together a booklet using all the most recent wjec maths exam papers, grouping all the questions from the same topics together.It is a huge document and it can be used for targeting the topics to tackle first. Pages in selected ranges could be printed off .It is the same as working on exam papers but concentrating on certain topics

Differentiated problem solving activity on the different averages. Three levels of difficultly Red, Amber and Green. Powerpoint with worksheets and answers. This is in line with the types of questions now asked at GCSE, but could easily be used with KS3. The students have to find the numbers that work given the values for certain averages. This is a good activity to consolidate understanding of the different averages.
