This is a twist on revision notes. I have written some notes and given examples but there are mistakes that the students have to correct. They must therefore read the notes very carefully and a partner must check their work. The idea is derived from an idea born from a discussion on Twitter (if you're not on Twitter, seriously think about it). I have split the notes up into three but I have included the whole thing so that you can chop them up your own way, or change stuff if you want. It&'s a bit of an experiment and we&';ll see how it goes!

They must therefore read the notes very carefully and a partner must check their work. The idea is derived from an idea born from a discussion on Twitter (if you're not on Twitter, seriously think about it). I have split the notes up into two bits but I have included the whole thing so that you can chop them up your own way, or change stuff if you want. It's a bit of an experiment and we&'ll see how it goes!

This is a revision aid where students must read the 'notes' carefully and find the deliberate errors (and possibly undeliberate ones!). I have split (with some overlap) it up into three parts going from 'what is an expression/identity/equation?', through simplifying, expanding brackets, factorising into a bracket, solving equations, multiplying out 2 brackets, factorising quadratics and solving quadratics (factorising, completing the square and the formula). The aim is to get them active in their revision!

The usual joke to find the punchline for but two sheets: sheet one is relatively easy whereas sheet two is all mixed numbers. Corrections made to codebreaker 1 - thank you for spotting them for me!

Clive is having a go at some homework regarding speed, density and population density. As usual with these it is a case of spotting Clive's mistakes, correcting then explaining what he has done wrong. They are designed to create discussion points in class.

Clive has two homeworks to tackle but is making mistakes once again. The first homework involves right-angled triangles, the second a question in 3D and non-right-angled triangles. Spot the mistakes, correct them and then explain what Clive needs to do in the future.

Clive is making silly mistakes again and it is down to your class to spot, correct and explain where he's gone wrong. This is designed to create discussion between students and teacher. This could be used as a plenary or a revision task.

I spotted a gap and have hopefully filled it. The usual “answer the questions to get the punchline” stuff involving conversion between metric units of length, area and volume.

Clive is tackling a simultaneous equations homework but as per usual is making errors. There are three sets of linear simultaneous equations to correct and a linear/quadratic to look at. I have tried to cover regular errors for students to spot, correct and discuss.

This is designed to lead on from finding nth terms of arithmetic sequences, getting students to spot a relationship from square and cube numbers. There are 4 sections each of increasing difficulty plus an extension task. This is not "superheroes" etc but should lead to nice discussions of "how do you know that?" and "how did you get that?".

This 270 slide Powerpoint covers all of the first year of the single A Level Applied course (based upon the Edexcel course). It includes explanations, worked examples and questions for students to do. I have included everything, possibly more than you may need but I’d rather give people the option to skip a slide than have to make something up on the spot. Colleagues of mine used this during the first year of the new course. The “Forces and Motion” part has been edited.

This 500+ slide Powerpoint covers all of the first year of the single A Level Pure course (based upon the Edexcel course). It includes explanations, worked examples and questions for students to do. I have included everything, possibly more than you may need but I’d rather give people the option to skip a slide than have to make something up on the spot. I used this during the first year of the new course.

Erica is taking A level mathematics but is making silly errors in her homework. Can your students spot and correct the errors, explaining what Erica has done wrong. These are designed to create discussion and reinforce understanding of the topics. This is thefirst A level version of "Clumsy Clive" which covers the GCSE curriculum.

Erica has a homework involving the sine and cosine rules as well as trigonometric functions. She thinks she's made mistakes; your students' task is to help Erica spot and correct the mistakes, explaining what she has mixed up. Designed to cover the new A level course and encourage discussion.

The Blue Darts Parallel and Perpendicular Problem is a GCSE worksheet on equations and gradients. The Blue Darts formation flying team want to plan a big finale to their display by creating an aerial rectangle. Can you help them find the equations of the lines that they need to fly along? What do you spot about the equations and their gradients?

Erica is struggling with algebraic division, the factor theorem and proof. She needs your help to correct her mistakes before explaining what she's done incorrectly. This is designed to create discussion and embrace the new curriculum that likes getting students to spot mistakes.

Eight quadratic functions to complete the square (including one where the coefficient of "x squared" is not 1) for students to do then plot the graphs. The aim is for them to spot how completing the square informs transformations of functions.

Can you spot which fractions shouldn't be in in picture?

Four matchings getting increasingly difficult at they go Firstly spot the correct formula for the correct triangle, the next two calculate a missing side and finally use Pythagoras to find the area of a shape. These have been designed to be used as starters or plenaries but you could use them as a main lesson activity; up to you.
