I've designed this lesson to build up students knowledge of simplifying algebraic expressions by collecting like terms.
It begins with a stock take scenario after a robbery and students having to find an expression for the value of missing items to give to the police. This is built up slowly with having to categorise the items not taken, think about quicker ways they could do this and then look at the difference between two stock takes of the items.
This then leads into a discussion of the definitions a variable, term and expression.
Leading to a discussion opportunity as to whether some expressions displayed on the board could be written differently.
There is then a true false activity to discuss and hammer out algebraic notation misconceptions.
Leading to 8 different examples of increasing difficulty fully modelled (Delete as appropriate for the class level) After each pair of examples there are two miniature whiteboard questions (16 mini white board questions in total)
This then leads to an interactive board game where the students have to come to the board or work in teams to select the expressions which simplify to make a certain expression.
There is then a tarsia activity attached.
The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 5 separate sections a skill 1& 2 and a stretch 1 and 2. These are all displayed on the same slide for ease of use.
Then to finish there is an application on how this could be seen in an exam situation including answers.
I hope you find this resource as useful as my students have.

Really helpful having the two versions - one 'spread out' so as not to overwhelm the students. A very helpful set of sources thanks!
