Various probability problems that help you defuse the infamous terrorist The Mathematician’s bomb. All self-explanatory and useful for a plenary or ‘Prove it’ activity.

Celebrity cracker eating - order the fractions to see who wins each heat and the series. Increasing difficulty of common denominator.

Erica's struggling again - please help her sort out her misunderstandings. This is, like all the others, design to create discussion and tap in to the new curriculum and question style.

Does what it says on the tin frankly.

I've been dying to use this pair from Disney&'s Brother Bear movie. Can you use the speed of sound to calculate how far away the nearest mountain is? Designed as a starter.

Hulk gets angry when he can’t spend time alone with y. Help Hulk rearrange the formulae so that can be the subject of his attention. I&'d like to thank the person who was brave enough to give me one star but not brave enough to tell me why so that I can try to rectify it.

I came up with the title on the sheet first and then built some maths problems around them. The grades for each are only to give an idea to the students, but hopefully it will get them thinking functionally.

Paying homage to the 24th outing for Britain's favourite special agent, here is Spectre Vectors. It includes resultant vectors, magnitudes of vectors and describing in terms of a and b. My GCSE class liked it anyway!

Four sets of four probability problems where parts of the question are missing but you have the answer. This is designed to get students thinking more deeply about topics and some questions allow for various answers which leads to differentiation as students can be asked to give the possible range of answers. This should lead to discussion in class.

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.

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).

Another “Crack The Safe” activity but on congruence and similarity this time. This enables students to self-check answers as their answer needs to appear in the options. It should generate a bit of discussion too, but the intention for me is to use these as starters or plenaries. Amended question 2.

It's always a challenge to make constructions interesting and seem relevent so I came up with this. Not sure it&'s hugely more engaging but it&';s something!

Cut out and play activities with blanks so that the students can make up their own questions.

Read this piece of news item from the BBC Sport website, then answer the questions, mainly about percentage change.

Estimate how much money I have left and whether I can make the return train journey on my shopping trip to London.

Just the three "spiders" on bearings, of increasing difficulty. The final spider asks students if they can write the question based upon the information given which may lead to a nice discussion in class.

Calculate the answers to each problem, use the table to change the answers to letters and then unjumble the letters to make a country. This is aimed at foundation GCSE or KS3 and involves simple powers (squares and cubes) as well as Bidmas.

There are 6 spiders here: two on speed, two on density, one on population density and one on pressure. This is designed to create discussion as well as offering students the opportunity to practise new skills.

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.
