I’ve no idea where I got these (if they were yours then message me and I will give credit as it’s certainly due) but I only had a paper copy so I have typed them up because I use them every year. They do exactly what they say on the tin. I have added my own one with slightly harder shapes entitled Cake Joke, but it’s the same thing (error corrected).

That terrorist, The Mathematician, is at it again. Make sure that you cut the right coloured wires to save everyone! This involves basic linear graphs, through more complicated linear graphs to quadratics and non-linear graphs (cubics, reciprocals and exponentials). My students seem to like this Defuse The Bomb concept, so as Simple Minds said in the Eighties, 2 Unlimited in the Ninieties, and just about any artist since the Millennium: if it ain't broke, don&'t fix it.

The terrorist, ‘The Mathematician’ has left clues to how you defuse the bomb 0 you must cut the wires in the correct order. Working up from simple ratio up to proportionality via three worksheets.

A couple of statitstical graphs regarding the World Cup with some questions that I've come up with for my class(es); I&'m sure you could come up with different ones if you wish. The website I got them from is very USA-centric but interesting and could be used as a numeracy resource or cross-curricular stuff.

WITH CORRECTIONS! The notorious terrorist ‘The Mathematician’ has left a clue to defusing the bomb he’s just planted. Answer the questions and cu the coloured wire in the correct order. This goes from purely Pythagoras, through Pythagoras and Trigonometry up to Trigonometry in non-right angled triangles.

Three different activities, each with five questions and a choice of three answers. They must scan the QR code associated to the correct answer to get the next 'colour' in the code. Activity 1 is wordy but relatively easy, Activity 2 a little tougher and Activity 3 that hardest (including factorising quadratics).

Three sheets varying from basic up to difficult. Angles 1 - lines, around a point, triangles. Angles 2 - parallel lines, polygons. Angles 3 - circle theorems. Each QR code links to a song where the band or song contains either a number or colour and they must find the final code. Could lead onto questioning and explanations as to how they arrived at their answer.

I have included two versions of this worksheet, one with smileys and one using some awful pictures of myself that will make the kids laugh! This aimed at lower ability students and offers a way of using a number line to add and subtract numbers.

The students have to answer the questions to know which order they ought to cut the wires to defuse the bomb left by the Mathematical terrorist who has left some clues for you.

Three worksheets going from writing in standard form, converting from standard form and calculating in standard form.

I got this idea from Tristan Jones @tris206 who had similar thing which I liked on TES, so I produced my own. I have purposely used a quite obscure joke so that it can't be guessed! The transformations involved are reflection, rotation and translation. For those who downloaded it very quickly, there's a second one!

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.

Follow the instructions to find the punchline for my Christmas joke - all the symbols that require transforming are Christmas related.

I've decided to do some maths stuff based upon US crime drama shows and this is the first based on differentiation, covering differentiation (including negative indices), gradients at certain points, turning points (maximum and minimum) and finally increasing/decreasing functions at certain points. The worksheets aren't massively necessary as it's been designed to work from the powerpoint but they are there to give you the option.

This is purely codes, using various "famous" codes including Caesar cipher, Pigpen, Semaphore, Atbash (the alphabet backwards) and one just written backwards. Each time the culprit is number 18 and I have left the names blank so that you can fill in with names of your choice.

A progress sheet to print out, questions on various topics to check knowledge and focus revision in the places where it's needed. This starts at probability scales (G/1), probability of an event (E/2), expected successes, one event OR another, relative frequency, sample space diagrams (all D/3), tree diagrams (C/4), one event and another (B/5), tree diagrams for independent events (B/6), tree diagrams of dependent events (A/7).

Help out the famous Wetherfield residents with their data issues by drawing and using scatter graphs.

The second in my US crime drama series on negative numbers. Pretty simple stuff involving temperature differences and temperatures being "n times colder". No real need for the worksheet unless that's what you prefer as it's all on powerpoint.

The usual stuff, solve the problems to discover the punchline to the joke. I use for a starter or plenary or occasionally a homework.

Three different codes to crack: number 1 is just finding the next term in the sequence (not all are arithmetic), number 2 is substituting into nth terms (with a simple quadratic or two) and number 3 is finding and using nth terms of arithmetic sequences. Each has a punchline to a joke to find. I use these for starters and plenaries or homeworks as they are very easy to mark. Typo on number 1 corrected.
