A presentation that introduces the main points about arrangements.

A dice game testing pupils' ability to substitute and to investigate expressions.

Generates an infinite amount of linear equations, with different levels of difficulty, and provides the answers. the only problem is that the answers are sometimes nasty decimals!

This a rich, Arithmagon activity on Multiplying Fractions. 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

A set of grids for working out sums using the method of chinese multiplication (or napier's bones) kindly donated by Nick Martin.

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

Algebra Level 6 Algebra Level 7 Expanding brackets Whole class activity Randomly generates all different types of brackets for students to expand and simplify. also gives answers

A nice bingo game to add some spice to practicing averages.

Number Level 5: Tests students' ability to add, subtract, multiply and divide with negative numbers by generating random questions and providing the answers. can be used for whole class teaching or to generate worksheets

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/blog/probing-maths-questions-index-page/

A lesson, complete with an interactive example, for teaching cumulative frequency and box plots.

Some ideas and examples of oral and mental starters which can be made applicable to all ages and abilities.

A Collective Memory activity on Level 5 Probability. A simple PowerPoint slide using the example of a pack cards to teach probability. This one contains missing answers. Thanks to Joe Ellis for this one!

A good challenge that tests knowledge of rotation, reflection and translation.

The computer rolls two dice, adds the scores, and keeps a record of the results on a grid. Good for playing bingo and introducing sample spaces.

Teaching the forming and solving of simple linear equations via 'i think of a number'.

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!
