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.

This a rich, Arithmagon activity on Addition. 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.

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!

students must shade in squares in order to form patterns with one or two lines of symmetry, or orders of rotational symmetry. patterns are randomly generated and answers are automatically checked

A Tarsia activity on changing the subjet of formula. These type of activities can be used to consolidate understanding of a given topic, and foster positive group work and co-operative learning.

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.

A nice little warm up activity about which is most likely that can lead to some nice discussions.

“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

Ten interesting real life estimation questions. Engaging activities to help pupils with estimations.

The 48th in Mr Barton's Autograph Video tutorial series. In my opinion, there is no better way of illustrating the concept of Volumes of Revolution to students than using Autograph’s unique 3D engine. Watch their delight at the area under the curve spins neatly around the x-axis to form a lovely 3D shape bringing what can be a very abstract concept to life. This video will set us up nicely for next week when we look at how to use Autograph to derive the Volume of Revolution formula. Clicking on the web-link you can see all the videos in this series.

bingo questions and cards where the answers rely on knowledge of parallel line angle facts

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

Earliest recommended Year group: Year 8. Bisect the sides of a quadrilateral to get a parallelogram. All quadrilaterals are different but all parallelograms are identical. The grid allows easy bisection 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!

A tricky puzzle, to really get pupils thinking. Great as a group task. Students have to use geometrical reasoning to find unknown lengths and work out the area of various triangles and quadrilaterals.

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.

Using ICT in Maths. The 45th in Mr Barton's Autograph Video tutorial series. This week we continue our look at the world of 2D graphing by examining how we can use the tangent tool and the gradient function to investigate quadratic curves. This offers a slick way of illustrating why two quadratic curves have the same gradient function. Clicking on the web-link you can see all the videos in this series.

Earliest recommended Year group: Year 9. Bisect the sides of a quadrilateral to get a parallelogram. All quadrilaterals are different but all parallelograms are identical. A compass will be needed to bisect the sides. 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!
