Simplifying expressions - collecting like terms

This is a full lesson based on 80 mins but you could alter it for your own lessons. It starts with a finding the perimeter activity which they should be able to do and will need for when you move onto the extra practice qwizdom. There is then a learning objectives slide followed by a match up activity which looks at the language of algebra and how to express information. This is followed by examples that get slowly more difficult before moving onto a notes slide that they can copy into books. There are then some differentiated questions to try. The extra practice activity is a multiple choice qwizdom that links perimeter of shapes with simplifying algebra as this is often seen in exam questions. The plenary is an exit ticket, there is a word document so you can just print those off.
