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.

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.

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 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 presentation just takes you through definite integrals and uses questions from Edexcel; please don't expect anything flashy. If the animations get mixed up I apologise but for some reason Equation Editor doesn't have square brackets onto which one can put limits! Annoying.

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.

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

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).

Six "spiders" on probability. The first two are basic, the middle two are two events (independent) and the final two are two events (dependent). Some "legs" answer questions, some legs give the answer and ask for the question. They have been split this way so that you can use different "spiders" with different classes. These should encourage discussion and questions such as "Is that the only answer?" which should demonstrate understanding. Typos corrected.

This takes students from fairly straightforward area and perimeter questions (trapeziums, circles etc) through compound shapes and on to cones, frustums and hemispheres including finding the height in terms of the radius for a cone. I have tried to cover all bases with it including density and capacity problems.

This leads students through graphing trigonometric functions, transforming f(x) and transforming a trigonometric function. The graphs are as big as I can make them in the format given so sorry if they are a bit small. I used Desmos for the graphs if you are interested (it’s brilliant!).

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 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.
