This is a “Tarsia: Convince Me” activity on adding fractions Unlike standard Tarsia activities, here you only need to print out the solution (included on the PowerPoint), and students must: 1. Find (at least) 5 incorrectly matched up elements, convince you that each one is incorrect explaining the mistake that has been made, and then decide what the answer should have been 2. Replace the ? with the correct answer 3. Come up with a question to replace ?? that could give the answer. A selection of these questions can then be given to other students to use as a rich, challenging, pupil-created homework.

Algebra Level 6: Challenges students to continue sequences, describe them and find the nth term formula. Great as a plenary or starter. Whole class activity, pupils could work as teams.

An interactive presentation covering the properties of basic polygons.

An exercise in index notation kindly donated by Vikki Sutton.

Lots of equations involving brackets to match up to their answers.

This a rich, Arithmagon activity on highest common factor, linking in lowest common multiple and prime numbers. 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

This is a rich Venn Diagram activity on equivalence of fractions, decimals & percentages. To access all the Venn Diagram activities in this collection, as well as teaching notes, please visit: http://www.mrbartonmaths.com/venn.htm Here is why I love Venn Diagram activities so much: 1) Students can always make a start. If they can think of a number/expression/object or whatever it might be, it has to go in one of the regions on the diagram, so they are up and running 2) The more regions student find, the more challenging the task gets, which adds a nice element of differentiation 3) They are incredibly versatile, and can be used for almost all maths topics for all ages and abilities 4) They are easy to tweak by simply changing one of the circle labels if you find they are too difficult/easy 5) Students can create their own as an extension task I hope you and your students enjoy them.

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!
