If you've done these before it follows the same pattern. If not, you show the screen for 30 seconds, they look in silence (without writing anything). They then get everything down on paper. Show the screen a few more times. Judge at the end. Instructions are on there.

The Mathematician, that notorious terrorist, has put a series of bombs around the country, but each has a clue to defuse it. These cover many aspects of fractions, decimals and percentages and are numbered so that they get increasingly difficult. As I say, my classes like these as starters/plenaries, hence there are so many.

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.

Find the lengths of the tunnels using the Sine and Cosine Rules. The students have to decide which to use with the information that they have. An attempt to show a use for the mathematics in a real life sense.

Calculate the distance the beams of light must travel in my warehouyse and the angle they make with the ground. This was just an activity to finish off this topic. There is an extension too.

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.

This was my attempt to get a worksheet that incorporates all the basic loci: perpendicular bisector, angle bisector, from a point and shading a region. You could add stuff if you like, but I ran out of room for the instructions, hence just the 4 tasks. The answers are rough based on the ones I did with pencil and compass.

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.

This is using the famous racing game to revise angle properties with parallel lines.

I was trying to make fairly simple angles problems a little more interesting through the medium of Star Wars for a lower ability class and this is what I came up with. Angles on a line, angles around a point and parallel lines. For those who are Star Wars experts, I've been liberal with a few facts but for a reason.

A simple sheet where they have to link the shape to the properties - made for a purpose but other may find it useful.

Colour in question number if it's even, leave blank if it&'s odd - the usual caper. It covers rectangles up to circles with parallelograms and trapeziums in between. Links to Then Jericho&';s timeless classic 'Big Area' on YouTube.

I found the cartoon on the first slide on Twitter (I'm sorry, I forget where) and I thought that my students could probably brush up on their Pythagorean triples like Batman. This was the result. The Powerpoint is animated and the Notebook file has screen shades, depending on the software at your disposal and your preference. There is a table of answers on the final slide of both files too.

Pretty dull worksheet but done for a purpose - it shows two methods of long division.

Whilst perusing Twitter after England's heavy defeat to Australia I came across this graphic posted by @skycricket which gave me the idea of using it for a maths discussion on data. You don&'t really need to know anything about cricket, just a basic understanding of statistics. It is designed to encourage some literacy and explanation.

Not the most exciting but worksheets to help with two different ways of performaing long multiplication calculations: Grid Method and 'Chinese' Method (feel free to rename them if you know them by any other name).

Do the points lie on the graphs listed? Follow the instructions and then scan to link to the Johnny Cash classic 'Walk The Line' (do you see what I've done there?).

Find the answers, colour in the correct squares then scan to get Madonna’s ‘Substitute For Love’ (the best I could do). QR code generated using qrstuff.com.

Find the next term in each sequence - if it is even, colour in the square, if not, leave it blank. Use a QR scanner and it links to a great song by Andy Burrows called ‘Keep On Moving On’, which was as close as I could get to a song about sequences! I generated the QR code using qrstuff.com.
