This takes students through percentage of an amount, one number as a percentage of another, percentage increase and decrease (including multipliers), percentage change, repeated percentage change and the reverse. This should be more challenging as the students go through it and should produce discussion.

This was designed as a "taster" session to A Level mathematics for Year10s/11s and builds on what they should know regarding expanding brackets until they discover that you can use Pascal's Triangle to expand brackets. It gives them the chance to investigate their theories and what effect a negative sign makes.

I needed something for my top set Year 8 to get their teeth into regarding "order of operations" and since I'm clearly into spiders at the moment this was born. It asks student to place operations and brackets into calculations to make them equal a certain total. There are 4 that get increasingly difficult (no indices involved) and then a challenge (with indices involved). There will also be more than one way to answer some, but I have provided an answer for each.

Fill in the blanks to simplify using the rules of indices. This should create some discussion in class regarding negative indices and how they could be written.

I got a request to do an activity using the A Team, both old and new. This is it! Convert each unit so that either 'old' or 'new' A Team understands. The numbers are pretty simple and it is designed to be a starter or plenary.

Six matching activities that get increasingly harder. Not all match which means that "process of elimination" cannot be used by students. This involves listing integers based upon an inequality and solving them too. This is an activity designed to encourage discussion. Now with quadratic inequalities slides! Errors corrected (I hope).

This moves through fairly easy to expanding two brackets via 8 different matching activities. This should give students the opportunity to discuss their thoughts and demonstrate their understanding.

Five matching activities involving the Sine Rule, Cosine Rule and finding the area of a triangle using trigonometry. These are designed to show learning/demonstrate understanding whether as a starter or plenary but could be used all together as a lesson's main activity.

This was an idea one of my Year 10s gave me using the "Mean Girls" films. This covers basic mean, median and mode before moving on to stem-and-leaf (including IQR) and grouped data - there are three very distinct sections moving up in difficulty to enable you to start/end where you like. It's all on the powerpoint to save the planet (no worksheet) but everything can be copied and pasted to create a worksheet.

From drawing the next pattern to finding the nth term of an arithmetic sequence. Enjoy!

This is designed to get students to think about algebra and substitution as well as knowing properties of number. This is looking at what you can substitute into an expression or a formula (so that rearranging is involved) to produce a given property. This is intended to create discussion and each question has multiple answers, some of which could be generalised therefore creating extra challenge for those who require it.

This came about after a colleague of mine (a Spurs fan) was moaning about a VAR decision that prevented Spurs from winning a Champions League match. Another colleague (a Brighton fan this time) suggested we check the errors in measurement and this was born. It is a bit of an experiment and I am aware that error is built in to the systems but I thought it was a nice practical use of something we cover in GCSE Maths. There are four scenarios: one tennis, two cricket and one football; questions are quite wordy but need to be to explain the laws of the sports in question.

Six spiders on surface area and volume (3 of each) and a final "problems" spider. They are of increasing difficulty, moving from cubes and cuboids to prisms to cones, spheres and pyramids. These are designed to avoid students getting into a rut of performing a mathematical recipe by asking a mixture of finding surface area/volume to working backwards. These usually encourage discussion in class.

All triangles and quarilaterals plus a regular polygon slide with 8 statements that students must decide whether they are always, sometimes or never true. This should create discussion. I have said that squares are a type of rectangle, and a rhombus is a type of parallelogram.

Tutorial with questions taking you through primes, multiples, writing and reading numbers, directed numbers (negative numbers), prime factors, HCF and LCM.

This takes students through factors, multiples and on to HCF and LCM. Hopefully this will allow students to work out what HCF is themselves.

No real imagination here, just a quick worksheet to stop the students bisecting a horizontal or vertical and bisecting a right angle. Don't expect anything fancy people...

This should bring about plenty of discussion. Four "spiders" of increasing difficulty asking students to complete a list of numbers to make the average and range properties true. A couple of typos corrected.

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.

I did this having seen numerous poor attempts at sketches in books on recognising types of graph.
