Clive has a histogram homework for your students to check. These are designed to get students discussing and thinking about the mathematics. I have also designed this to work online as there is minimal drawing involved (although there is a little).

Clive is looking at some questions on linear graphs, but as usual he is making mistakes that your classes need to help him with, explaining what he has done incorrectly so that he (hopefully) doesn’t make the same mistakes in the future. This is designed to encourage discussion and help students to develop a deeper understanding of the topic.

Clive is tackling two tests on surds and indices; the second is more challenging than the first. As usual he is making mistakes and needs your students’ help to explain what he has done wrong and show him how he should have completed the questions correctly. These activities are designed to create discussion and develop understanding and model the new style “spot the error” questions that now appear in many exams.

Clive is tackling number in these two tests, including properties of number, HCF, LCM, prime factors, Venn diagrams and the product rule for counting. As ever he is making mistakes and needs help from your classes to help him correct his errors and then explain what he did wrong so that he (hopefully) doesn’t make the same mistakes again. This is designed to create discussion.

Clive is having a go at a couple of ratio and proportion tests but making mistakes as per usual; he desperately needs your help to set him straight. These are designed to create discussion in class using common mistakes. There are two tests, the second being more challenging than the first. The first concentrates on ratio whilst the second concentrates on proportion.

Clive has a homework on function notation involving domains, ranges, inverses and composite functions. He has, as per usual, made errors that your class can find, correct and explain so that Clive learns from his mistakes. These are designed to create discussion in class and this one could be used as a transitional activity between GCSE/IGCSE and A level.

Clive is having a go at quadratics questions now; these involve expanding two brackets, plotting graphs, factorising and solving on test 1 before moving on to more solving, using the roots, completing the square and using the quadratic formula. Clive is prone to making mistakes so your class has to spot these and explain what his mistakes are so that he learns from them.

Clive is having a go at some revision tests on some basic algebra, including simple algebraic fractions, like terms, expanding brackets, solving linear equations (including with variables on both sides), expanding two brackets and substitution. He has made a mistake on each question; your class needs to spot the error, correct it and then explain what it is. These are designed to encourage discussion in class and develop deeper understanding using common errors.

We are starting to see more and more questions at GCSE asking students to spot and correct the mistake made. Clumsy Clive and Erica’s errors problems by @andylutwyche for are a perfect way to tackle this and I have edited and collated them togther. “Erica has made some silly mistakes on her homework. Your students’ task is to find the errors, correct them and explain what Erica has done incorrectly. This should generate discussion in class.”

Dounble homework this week for Clive as he tackles algebraic fractions; he's having a complete nightmare to be honest. Can your class help him out and explain where he's gone wrong? These are designed for starters or plenaries and encourage discussion in class. The second sheet is at a higher level (quadratics etc) than the first.

Clive is tackling a bit of substitution but making mistakes again. Your students' task is to help Clive sort out his errors and explain to him what he's done so that he doesn't make the same mistakes in the future. Ideal for starter or plenaries and encourages discussion.

Clive is having a go at simplifying expressions, without complete success. Your task (or more accurately, your class' task) is to help Clive correct his homework and explain where he's gone wrong. Good for starters or plenaries and encourages discussion.

Clive is doing some homework involving error in measurement and is getting a bit confused. He has made some mistakes that you need to correct and explain to him where he's gone wrong; the homework contains just stating bounds as well as calculations that require thinking more carefully about. This really makes students check their explanations and generates good academic discussion in my experience as well as allowing students to demonstrate the depth of their knowledge.

Clive is having more issues, this time with decimals, and a little bit of fractions and percentages. This involves ordering, adding, multiplying, dividing and recurring decimals. Clive needs someone to explain what he’s got wrong. This should encourage students to demonstrate their understanding.

Clive is having issues with percentages, including "of a number", percentage change, repeated change and reverse percentages. Please help Clive correct his work and explain what he's done wrong. Designed to create discussion and allow students to demonstrate their thinking/understanding.

Clive is getting confused with fractions, fraction of an amount, adding, subtracting, multiplying and dividing. This designed to get students to explain their reasoning and should encourage discussion.

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.

These are all available for free individually but if you don’t have the time then this is for you. Clive makes common mistakes, mistakes you’ll have seen in class. Your students need to find the mistakes, correct them and explain where Clive has gone wrong so that he doesn’t do the same thing again. These activities are designed to create discussion in class and can be used to assess understanding.

Clive is still struggling to get his homework right, this time rearranging formulae being the issue. Your task, or more likely, your students' task (should they choose to accept it) is to check, correct and explain where Clive has gone wrong. Designed to create discussion in class and to check understanding.

Clive is doing some vectors work this time and is confused once again. Can you check all his answers, correct them and explain where he's gone wrong. He's made some typical mistakes which should get everyone (students and teacher) talking.
