I have collated a powerpoint on expanding brackets. It is a simple resources and can be used with all year groups (depending on ability). It starts off with expanding one bracket then goes on two expanding two brackets with collecting like terms.

I have put together a resource on simplifying expressions by collecting like terms. It starts off with introducing like terms then goes onto simplifying them with one variable and more than one variable. There a shape problems to stretch the most able.

I have cerated a simple resource for students to understand algebra notation and vocabulary. Feel free to edit it for your year group/set. It starts off with function machines and then introduces algebra. There are practice questions and it ends with the algebra vocabulary and a exam question.
