Lots of linear equations of varying difficulty to match up to their answers.

A domino match-up for diving ratios of amounts.

A fairly simple jigsaw simplifying expressions with numbers and one variable.

An exercise in index notation kindly donated by Vikki Sutton.

Pupils must match the description of the polygon to its name.

Match up equivalent fractions, decimals and percentages like dominos.

A jigsaw containing some pretty easy and pretty hard place value questions.

An excellent lesson on the binomial distribution, following the SMP S1 book, kindly donated by Lisa McNulty.

Pupils must match up outcomes with their probabilities.

Separate worksheets show the different forms quadratic graphs can take and how this determines their key graphical features.

a nice starter activity where students must decide the order of other students' answers

Earliest recommended Year group: Year 13. Pupils are given different segments of circles and asked to calculate their volumes of revolution. They all have the same volume. This is from the “Something in Common” collection of resources by John Burke. They allow consolidation of key skills, prevent students from copying each other (as all the questions are different), make marking and assessing easy for the teacher (as all the answers are the same!), and provide a lovely extra challenge for students as they try to figure out exactly what is going on!

This is a “Tarsia: Convince Me” activity on adding, subtracting, multiplying and dividing 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.

a bingo game which tests students ability to work out co-ordinates given the equation of a line. ive lost the relevant bingo cards, but hopefully will find them soon!

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

An excellent lesson on sampling and estimation, following the SMP S1 book, kindly donated by Lisa McNulty.

Examples of the use of percentages in the real world. Good as a starter.

“Build an Army” is a fun, strategy game that can be used to consolidate understanding of key mathematical concepts. After students have played the game and described their strategy, there are opportunities for differentiation via various lines of inquiry and probing questions for the students to investigate. Full instructions are provided in the “General Rules” PowerPoint. To find more Build an Army activities, just visit: http://www.mrbartonmaths.com/buildanarmy.htm

A Tarsia activity on algebraic fractions. These type of activities can be used to consolidate understanding of a given topic, and foster positive group work and co-operative learning. For more ideas on how to use these types of activities (including twists!) and to download the latest version of the wonderful free software to open this resource (and create your own), just click on the web-link. If you have any comments, or spot any (non deliberate!) mistakes, please share them below. Many thanks to all the teachers who have helped me assemble these Tarsias over the years.
