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

Calculate these proportional relationships involving Superman and his proximity to kryptonite as well as his rating in the criminal underworld. An attempt to liven up proportion with my Year 11s.

This is a great GCSE activity in which students match each equation to its gradient, y-interceptor and the co-ordinate on it. I wrote this in order to get across the idea of y=mx+c plus the fact that it describes the link between the x and y co-ordinates.

Look at the fourteen statements and decide whether they are always, sometimes or never true.

Convert mixed to improper and vice versa. The usual stuff - find the Tim Vine joke punchline...

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!

Answer the differentiation questions, find the letters and reveal the punchline to a (terrible) joke. My class in Year 12 actually request these only to groan enormously when the answer is revealed. Just meant for a bit of practice, a starter or a plenary. Version 2 contains second derivatives.

Insert the numbers in the correct positions, making the calculations correct to win a roast dinner for the hungry camp members. Thank you for all the feedback about the confusing wording. I have changed it so hopefully it now makes more sense!

In these worksheets the various questions use how many songs you can get onto an MP3 player (1Gb = 250 songs) to look at ratio. Leads onto other questions involving fractions and percentages.

Using the fact that Ant-Man shrinks and grows, I produced this calculus resource on rates of change. Two situations regarding Ant-Man's suit: surface area of the suit itself and the volume of the helmet.

A simple worksheet to practice reading and writing numbers in standard form using the calculator context. I have included the Word documents but the text might not appear in "calculator font" as I had to download a special font (just Google "Calculator Writing Font" and it's the first link and free from a company called "Digital 7").

Find the words and use them to complete sentences. Designed for lower ability in secondary school who will then have some notes too!

A relatively simple activity of putting X-Men's enemies into Venn diagrams, not using any of the notation.

Enlarge the shapes and produce a rather simplistic picture. There is a sketchpad file to go with it in case you have Geometers' Sketchpad.

Calculate each team's final position in the race by substituting in a value of your choice. There's a bit of algebraic proof in there too to see if the teams will finish in the same position regardless of the value substituted.

Calculate the answers; if even colour in the question number in the grid, if not leave it blank. It scans to the Depeche Mode song "Policy of Truth" linking in that we have "lies, damn lies and statistics".

Chocolate based inequality problems - 6 in all. Display on the board and discuss is how I envisage it working but you may have other ideas. I must thank Deborah @MrsMathia for the logo and initial inspiration!

This is based upon the concept of the gameshow called “Impossible” (I watch daytime TV in the holidays, sadly) where each question has three options: one correct, one partially correct and one impossible. I ask students to find the correct answer and then explain why the other two options are either impossible or only partially correct. This one involves algebra topics like simplifying expressions, factorising, sequences, equations of lines, inequalities, quadratic equations, function notation, rearranging formulae etc. There are twelve questions altogether.

Answer the questions about truncation to reveal the punchline to a cheesy joke. These are popular in class in my experience.

The usual “answer the questions, reveal the punchline” this time involving finding the equation of a normal to to curve.
