Objective: Simplify algebraic expressions by collecting like terms and then simplifying.

I've given the answers but they are not fully correct or they are incorrect. The students need to identify the errors and make them right. As an extension ask them to pick a question and write up a really good explanation of how not to make that mistake again.

Answer Sheet included :)

11 questions which identify particular types of questions like "a- a = 0" and not "0a", etc. The questions are copied from an excellent worksheet published by mathsmalakiss. I've used his/her worksheet which you can download yourself.
