These spiders (there are seven of them in total) take you through simplifying, calculating, rationalising denominators, expanding brackets and rationalising "tough" surds.

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.

The usual story but with some Bidmas/Bodmas questions. If you’ve not seen these before then the students must answer the questions correctly in order to know the order in which to defuse the bomb.

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've been itching to do a maths 'Games of Thrones' thing for a while and then this popped into my head. Fraction of a number, comparing fractions and adding and subtracting all in the name of an ice cream war!

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.

Using the 'Chart of the Day' page (linked) I have set some questions on real life data. I'm sure you could all come up with better questions, but hopefully this will give you a start.

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.

Complete the calculations, solve the anagrams and find the punchline for a joke! A couple of typos corrected now.

Ice Cream issues again for Lark Ices and Stannister Dairy who have some dodgy software that keeps going wrong, hence the need for them to estimate and round. Goes from simple rounding, through estimating calculations to upper and lower bounds.

The two bands are comparing notes with regards being in a band in different eras. The 1D boys work in metric, The Stones in imperial. Can you convert units between metric and imperial (and vice versa) for each band?

Independent student revision activity. Solve the problems, unjumble the letters and plot my path around Europe. Great revison for number topics. Order of operations, finding fractions/percentages of an amount/quantity, equivalent ratios. SSM Shape geometry, calculaing area and perimeter. Statistics calculating averages.

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.

Please excuse the pun in the title but I can't believe it&'s not been done before (maybe it has and I&';ve missed it). Various locus related situations for Thor to navigate in order to defeat Loki's recruits.
