This was an idea I had in on the way to work one morning - Clive makes mistakes on his homework and you need to correct them, explaining the mistake he's made in each case. I intend to use this as a plenary or starter to check learning etc. They should create discussion too. There are 5 different mistakes to correct.

Give Santa the correct three figure bearing for each stage of his journey.

This help William 'Billy' Black calculate how much grease-proof paper he needs plus how much each cake tine can hold. The shapes go from cuboids to a cylinder to a hemisphere to a frustum, so you can start and finish where you like.

Four of Clive’s “homework” sheets to correct and explain where he’s gone wrong. There are four to complete: a “basic” one, one on parallel lines, one on polygons and finally one on circle theorems. The basic and parallel lines ones have 5 questions to correct; the other two have 4 questions to look at. These are designed to encourage discussion between students and then to share that discussion with the teacher as there’s not always one way to correct a question. I introduced these before the holidays and they went very well.

This was an idea I had in on the way to work one morning - Clive makes mistakes on his homework and you need to correct them, explaining the mistake he’s made in each case. I intend to use this as a plenary or starter to check learning etc. They should create discussion too. There are 5 different mistakes to correct on two separate sheets; number 2 cover negative and fractional indices.

I always struggle for something a little different for recurring decimals and although this is the same old thing dressed up differently it might make them keener to complete the questions!

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.

The Avengers need your help to display this data successfully, and also calculate some averages etc. This builds up from low ability to high ability in stages, but is designed to be 'dipped into' where you need to. It covers from bar charts, through scatter graphs and frequency polygons, up to histograms and contains the calculations that go with each. The teachers' notes are just as a guide and don&'t need to be adhered to, but I have tried to guess the kinds of calculations that students might perform. Transparency of the title pages sorted!

Two trigonometry codebreakers that both involve a terrible joke. The first one is with right-angled triangles, the second requires the sine rule, cosine rule and area of a triangle using trigonometry.

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.

Solve the problems, unjumble the letters and plot my path around Europe.

Find out who stole the satsuma from my stocking by solving all the clues (it will always be person 14 by the way). I have left the suspect sheet blank so that you can enter the names you wish; I've used classes, colleagues, celebrities when I've done similar things. Each clue eliminates half of the remaining suspects and should take around an hour depending whether you let them use a calculator or not.

A student asked me to do a resource involving Harry Potter; we are doing unit conversion soon so this is what occurred. There are two tasks, one converting metric units (including a challenge involving areas and volumes) and a second converting between metric and imperial. I downloaded a font from dafont.com for free so if you want to edit the worksheets (I have included the Word versions so you can do so) you will have to download the font too.

This was born out of an exam question that asked students to work the quadratic formula backwards (ie. from simplified quadratic formula to original equation). I have hopefully scaffolded this appropriately. The second page, a matching activity, asks students to link a quadratic function to it’s roots/solutions. I’m rather hoping that the link will become obvious to the students, but who knows?! Either way it should lead to some discussion about quadratics. Typo corrected!

An extremely lame joke but some Pythagoras questions to calculate. Eight questions in total so ideal for a quick homework, plenary or starter; four questions have diagrams and four questions are worded.

I found this poster with various numbers regarding the World Cup in Brazil and made this activity from it. Change the questions at will. I have also put a link to the website 'My Life In Numbers' as that has a new 'Live Event' measuring from the start of the tournament.

Clive's made mistakes on his homework again. This time it is on solving quadratics, including the quadratic formula and completing the square in the final two questions. Students need to find Clive's error in each question and involve common mistakes I've seen made in class and in tests/exams. These are designed to assess understanding and to generate discussion.

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.

This idea is from Craig Barton and is an excellent one (check them out his at website); essentially it is four questions based on the same information. There are four here which use fractions, ratio, percentages and averages as well as other topics. This really should create discussion and a deeper understanding of the topics covered on top of ensuring that students actually read the question. I hope these are worthy! I will be using these as starters or plenaries. I haven’t used logos to avoid any copyright issues. Hyperlinks added…

This idea is from Craig Barton and is an excellent one (check them out his at website); essentially it is four questions based on the same information. There are four here which use perimeter, area, Pythagoras, equations of lines, coordinates, vectors, equations of circles, expanding brackets, solving equations as well as other topics. This really should create discussion and a deeper understanding of the topics covered on top of ensuring that students actually read the question. I hope these are worthy! I will be using these as starters or plenaries.
