Some shapes' symmetrical properties need describing, starting with simple mathematical shapes and moving to other stuff (potential for discussion if you are that way inclined) and then completing a few diagrams to give them symmetrical properties (simple GCSE questions).

A really bad joke (I think I've surpassed myself with this one) but some practice on multiples and factors on this one. As I say on all of these they can be used as a starter, plenary, homework, discussion exercise, whatever you like basically.

Erica has straight line graphs homework but her answers don't agree with the answers given. Can you explain to her where she has gone wrong as well as correct her homework? This should lead to a discussion between students over common mistakes and misconceptions. My error (oh, the irony) is now corrected.

There was a gap in the codebreakers for straightforward compound shapes, so I did one… The usual stuff: answer the questions get a punchline to a lame joke.

This powerpoint uses two scenarios: building site and office. You can choose the order in which you do them or whether to do one and not the other. These are worded ratio problems to discuss and use to establish understanding or encourage verbal explanations from students.

This is a start or end of term activity just to stretch the mathematical hamstrings. Find the punchline to a joke by answering the questions.

Answer the questions and find my destination each time.

KS3 / GCSE Maths worksheet. Plot the squirrel from the Carling Black Label advert's journey and answer the questions. Video on both Notebook and powerpoint.

This is a task involving the four rules (add, subtract, multiply, divide) with negative numbers. Basically students fill in the blanks but there could be discussion about different answers etc.

This worksheet has six questions and eight answers to choose from (this is to avoid students guessing the final answer/answers) so that Santa can rest two reindeer for each trip. This one covers parallel and perpendicular lines and contains an answer sheet. I use these as starters/plenaries or as "prove you can do this topic" sheets. I have used them as quick homework tasks too.

This is designed to lead students through solving quadratic equations by completing the square from quite basic to difficult. The activity is also there to encourage discussion in class and helps them get into good habits regarding setting their solutions out.

I've been asked a few times what these are like so thought I'd put one of each "Number", "Algebra", "Geometry" and "Data" out there for people to peruse at their leisure. These are worksheets that can be used for either revision, homework or those students who have missed work with each containing a QR code that will scan to a short tutorial video.

This takes students through percentage of an amount, one number as a percentage of another, percentage increase and decrease (including multipliers), percentage change, repeated percentage change and the reverse. This should be more challenging as the students go through it and should produce discussion.

Three "spiders" - the first two are general using of the theorem and the final one is more problem solving. This should encourage discussion, especially the final one.

Clive has two homeworks to do on equations of lines but as usual he has made mistakes that need correcting and explaining so that he never makes those mistakes again. This is designed to create discussion and the second one is more challenging than the first.

Clive is getting confused on his homework again; this time it's sets and Venn diagrams. Your class' job is to check, correct and explain why Clive has gone wrong. This is designed to create discussion in class.

Clive is tackling a new topic on the GCSE curriculum, but predicatably is struggling. Four questions getting increasingly difficult requiring you to check as Clive has made mistakes. These will hopefully generate discussion in class.

Erica is struggling with trigonometric functions this time. these questions invlolve sec, cosec and cot and Erica is struggling. Can your class help explain where she has gone wrong. This allows students to demonstrate understanding and discuss their thinking.

Erica is struggling with double angle formulae, compound angle formulae - the works"! Can you help her sort out her homework and explain what is going on? Designed to encourage discussion.

Six maths "spiders" designed to test whether students can substitute in to formulae correctly. The spiders get increasingly difficult and are designed so that they have to think and possibly discuss their answers rather get on a "substitution treadmill". I know people use these for starters/plenaries and I have used them as tasks in lessons.
