OK, I know that Twitter isn’t Cool for Kids but I do like to get all my GCSE students to use it to follow Corbettmaths. Their school probably uses Corbettmaths resources for teaching. They are about the best of the bunch of resources.
Best of all they publish daily questions to test students’ knowledge, and are a great way to revise in a way that doesn’t seem like revision. No, revision shouldn’t just happen at exam time. It should be continual, to keep on top of learning.
So go take a look at their 5-a-day offering @Corbettmaths
