A Tarsia activity by Alan Catley. Basically a series of past exam questions but the first time this was used I gave all three terms. This was a disaster as the students were able to spot the matches by only finding the first two terms when the most difficult job is finding the third term. Changed to just giving the third term and it became a huge success as a consolidation activity.

two stage function machine with input and output which is a good way to introduce students to the concept of inverse operations and forming equations

Have a play around with this task, and please share any questions, extensions, simplifications, modifications, or lines of inquiry in the comment box below. The idea is to collect loads of suggestions that can then be used for effective differentiation. The full set of these tasks, along with additional notes, can be found here: http://www.mrbartonmaths.com/richtasks.htm

A few years ago I wrote a set of notes for pupils and put them on my website. The notes were supposed to be written in a pupil-friendly way, and different to notes students might find in textbooks or elsewhere on the internet. I have converted the notes to PowerPoint slides so you can download them, adapt them if needed, use them in revision lessons or perhaps give your students a set to take home with them to help them prepare for exams. The chances are there will be a few mistakes here and there, so if you spot any please email me & I will correct them. Hope they are of use!
