CIMT – from the University of Plymouth, an astonishing resource – free curriculum materials for all school-age students. Here you will find examples, exercises, teachers’ notes, activities…..
For example if we look at the Year 7 page as well as all the book chapters with their numerous worked examples and exercises there are also teachers’ resources including notes, slides, revision tests, activities and mental tests on each topic. The activities are varied and include investigative work.
There are also Interactive Tutorials available, useful for revision or perhaps if a student has been absent and several Topical Applications of Mathematics which include lesson plans and student resources. I have successfully used the resources on Braille.
On the subject of interactive materials – note the Step Up to A-Level Maths resources.
