A resource to be used regularly as revision for quadratics. Write a quadratic on the board and have pupils fill in the worksheet for that quadratic. The worksheet is colour coded for difficulty (green=easy, orange=harder, red= harder still, purple=extension) and the difficultly level can also be adjusted depending on the quadratic you choose (e.g. make a not equal to 1 to make factorising harder, make b odd to make completing the square harder, have them use the quadratic formula for solving etc). This could be done regularly with a different quadratic each time until they are confident. Suitable for KS4 or upper KS3.
