Two versions: one with words listed and one without. Use the words to complete the sentences.

Rearrange the formulae and reveal the joke (generous description in fairness). These formulae are not particularly tough to rearrange but should get across the principles of it; the subject only appears once in each case. Ideal for classroom activities (main task or starter/plenary) but I have used them for online lessons and homeworks as well.

This is an attempt to get students to fill out every stage of their rearranging process. There are six relatively basic questions then three more challenge on the reverse of the page (I did this so that I could decide whether they were suitable for certain classes).

Clive is having a go at some revision tests on some basic algebra, including simple algebraic fractions, like terms, expanding brackets, solving linear equations (including with variables on both sides), expanding two brackets and substitution. He has made a mistake on each question; your class needs to spot the error, correct it and then explain what it is. These are designed to encourage discussion in class and develop deeper understanding using common errors.

The usual: answer the questions to reveal the punchline to the joke. Can be used in starters, plenaries, main tasks and homeworks!

Calculate the fractions of a turn and the fraction of Spidey's enemies required.

This is a variation on a codebreaker; unfortunately the software (PowerPoint) won’t let me reflect words, but it will let me rotate them. The shapes fit together when transformed correctly and the words should form a cheesy joke.

Clive is tackling number in these two tests, including properties of number, HCF, LCM, prime factors, Venn diagrams and the product rule for counting. As ever he is making mistakes and needs help from your classes to help him correct his errors and then explain what he did wrong so that he (hopefully) doesn’t make the same mistakes again. This is designed to create discussion.

This is designed to get students thinking rather than getting in to a rut with this. There are columns for questions, factorising, a sketch of the curve and the solution; some are missing in each case.

Work out the equation of the line that the footballers kick the ball along in order to eventually score. There are two versions, one with the pitch and one without due to possible printing out issues.

Two fish jokes to find: one on quadratics graphs and one on other curves. Ideal for classroom in real life or online and also homework tasks.

The numbers from 1 to 50 are in the grid, if it's a prime number colour it in, if not leave it blank. The QR code links to The Cure's 'Primary' for obvious reasons: the name of the song and it&'s good.

A really lame joke this time, but that will surprise few. How many unique outcomes are there in each situation?

Clive is looking at some questions on linear graphs, but as usual he is making mistakes that your classes need to help him with, explaining what he has done incorrectly so that he (hopefully) doesn’t make the same mistakes in the future. This is designed to encourage discussion and help students to develop a deeper understanding of the topic.

These are some mainly worded Pythagoras and trigonometry (in right-angled triangles) questions that should hopefully get students thinking (and sketching the problem). I came up with the joke myself… I apologise.

The usual thing: answer the questions, reveal the cheesy joke. I use these as starters, plenaries and main tasks; you can use them (or not as the case may be) however you like… but students do seem to like them (if the volume of groans at the jokes is anything to go by).

Looking at shapes like rectangles, squares, triangles, cuboids and cylinders, fill in the missing parts of the table. This is designed to get students thinking rather than going into algorithm mode. I plan to make a second one with more complex shapes eventually.

Using the famous "Um Bongo" song from the mid-Eighties a load of measures questions, plus volume and ratio. Designed as a test of functional skills.

Two codebreakers on factorising quadratics, some of which are a difference of two squares. The usual lame jokes…

One fish pun on percentage multipliers and one on calculations (including percentage change). Useful for online learning or a classroom activity.
