This is a revision activity either to be done in small groups or individually. There are the following rounds: Number, Algebra, Shape and Space, Date Handling, Using and Applying. All have 10 questions worth one point each except the Using and Applying round where there are 5 questions worth 3 points each, where workings must be given.

These spiders (there are seven of them in total) take you through simplifying, calculating, rationalising denominators, expanding brackets and rationalising "tough" surds.

This is designed to make students think about representing inequalities on a number line, listing integers (directly and having simplified) and regions. They are split this way to allow you to start/stop wherever you feel your class needs to. The number lines and graphs are as big as I can make them!

A student gave me the title (pun on 'The Hunger 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. It's supposed to be non-calculator! I may do a sequel for this as there are a few topics I haven't covered.

This (hopefully) does what it says on the tin: I wanted some sheets for students to construct triangles and bisectors so produced this. The constructions all fit in the boxes provided as long as you print them out on A4 paper. We start with constructing triangles, then bisectors, then a rhombus and a perpendicular line from a given point before finishing with couple of challenges (Yin-yang, incircle and circumcircle). Like I say, it is not designed to be flashy just practical.

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.

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.

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.

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.

A comment from my trainee teacher made me think that rounding to decimal places and significant figures needed an activity, so I came up with this. It should get students thinking and should open up discussion on rounding, which can be a little "dry" but essential to get to grips with. Typo corrected!

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.

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.

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.

A series of real-life graphs that are misleading in some way. Nice for a discussion activity.

Practice on the function notation (new to GCSE!) involving substituting into a function and finding the value of x given what f(x) equals. This also involves composite functions. This should hopefully encourage your class to talk about their answers and understanding of the topic. Now includes an extra "find the inverse" slide!

The students are given the answer and asked to fill in the gaps in the question. Topics used involve probability, equations, simultaneous equations, fractions, percentages, ratio, speed, distance, time and many others. Some of the questions allow for multiple answers so discussion could be had. Designed to be used as starters/plenaries to get the grey matter moving. The Christmas theme runs through every question and is a tad tenuous at times but there you go.

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.
