The usual lame joke having done some maths; the formulae aren’t overly taxing but do involve powers of negatives. They are now formulae and not expressions.

Practice for the skills required to find a percentage of an amount; not difficult but designed for non-calculator use ultimately and checks skills such as multiplying and dividing by 100, decimals, converting between fractions, decimals and percentages before asking a few percentage of an number questions.

Another in the series taking students through the skills required to solve equations, including simplifying expressions, expanding brackets and reading the question carefully!

Taking students through the skills required to solve problems involving surds. There are questions that students will need to do without a calculator as the calculator will give them the fully simplified solution.

This takes students through all the skills required to solve simultaneous equations graphically (only linear graphs), by elimination and by substitution including one linear and one non-linear up to GCSE level. Work from the bottom building the skills up to the most complex style of question.

This does what it says on the tin basically; a load of right-angled triangles with missing lengths to calculate and reveal the fish joke. These work in class, online or as a homework task and reassure students as they start to spell a word or sentence.

Another fish related effort after finding the missing angles using circle theorems. Ideal for online lessons and in-person ones too; students like the cheesy jokes despite their protestations to the contrary.

Find the words in the wordsearch then complete the sentences using them. I'd use this as a "plenary" but don't let that influence you.

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

My daughter won this in a Christmas cracker (she was over the moon!) but it is full of sequences and I thought it would make a nice little activity for a class or two of mine.

Fenton the dog likes chasing deer and geese through Richmond Park (the original video from YouTube is included in the Notebook file). The Rangers need to calculate the number of distressed animals there are as a result of the chases using the total number of feet chased and the total number of animals.

Discover the punchline to the lame joke (I use it in class on a regular basis) by solving the equations involving brackets and fractional parts. I have got "Solving Equations Codebreakers 1, 2 and 3" elsewhere, uploaded a while ago.

I've recently discovered this in my folders on my computer. It is a 10 question non-calculator quiz using real situations.

Prevent Hulk from going on the rampage by simplifying the following surds!

A student gave me the title (pun on 'The Hunger Games' - original was 'The Number Games'), I did the rest. Five different sets of questions in a functional style for students to work through either individually or in pairs/teams.

This is designed to be used as a starter or plenary: Can you help Phineas and Ferb calculate the missing sides on the rollercoaters they are building? Dr Doofenshmirtz also needs to know if his Snailanator ray will hit Agent P.

This is for KS3 or low ability KS4 - I have put 2 versions on: one including my face and one with smileys. You can obviously swap the pictures for your own. I thought it might make simplifying expressions a bit more fun!

This KS4 quadratic graphs worksheet is Lara Croft themed. Work out the equation of the graph that needs to be programmed in to make Laura swing and then plot the other two graphs from the equations given. This is an attempt to bring quadratics into the world occupied by students.

This is a twist on revision notes. I have written some notes and given examples but there are mistakes that the students have to correct. They must therefore read the notes very carefully and a partner must check their work. The idea is derived from an idea born from a discussion on Twitter (if you're not on Twitter, seriously think about it). I have split the notes up into two bits but I have included the whole thing so that you can chop them up your own way, or change stuff if you want. It&'s a bit of an experiment and we&';ll see how it goes!

Captain America wants some new shields made. You have to calculate the area then volume of the shields. The rare alloy, vibranium, that the shields are made from is limited so using old, broken shields you have to calculate if he has enough of the alloy; this part is sectors of circles. I have intentionally split the activity into two so that you can stop after the initial areas of circles depending on the class.
