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.

A PowerPoint with Revision notes on solving linear equations at KS4. 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.

Lots of questions and answers testing all types of rounding.

Pupils must identify the mistakes made when setting out each of these four sets of scales.

Pupils must find a route to the target number by adding and subtracting decimals.

Four questions on integration with drop down menus to choose your answer. Highlights important misconceptions.

An interactive powerpoint presentation summarising and testing all the main skills required for success with fractions.

A nice crossword style activity testing knowledge of angle facts.

An introduction to writing expressions and collecting like terms via little stories.

Powerpoint presentation. A quick starter activity where students must estimate the sizes of several angles

This a rich, Arithmagon activity on Midpoints between co-ordinates. I love Arithmagons as they allow consolidation of key topics when going Forwards, and then opportunities for extension, creativity and discovery when working Backwards. They are also really easy to modify to suit the particular needs of your class. For all the Arithmagon activities in this series, together with teaching notes and extra information, please visit http://www.mrbartonmaths.com/arithmagon.htm

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.
