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.

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

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.

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 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 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.

This is an attempt to relate algebraic questions that children struggle with to worded questions they can all do. It is designed to start you off, building up from 'I think of a number' to a full blown linear equation.

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.

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

Six "spiders" on six different sets of angle properties starting with "on a line", "around a point", "triangles", "polygons", "parallel lines" and "circle theorems". The final two require students to name the property used and I have left a couple of the parallel lines with the answers filled in so that students can draw their own diagram. The activity is designed to create discussion.

Four sheets (two with mixed numbers, two without) to practise multiplying and dividing fractions. This is just a different way of doing some questions and depending on how it's run can involve plenty of discussion.

There are four "explosions" for students to deal with, each covering different types of algebraic fraction. The first slide involves simple indices and simplifying, the second involves adding and subtracting (find a common denominator), the third has algebraic expressions as denominators and the fourth involves factorising quadratics. These are designed to stop students getting in a rut of doing the same thing over and over again, plus they should (hopefully!) generate good mathematical discussions.

I’ve called this an “Advent” calendar as I couldn’t think of a better name, but I have little intention of using it in the run up to Christmas only. There are 24 questions which you can choose to display; students have a go and can then check their solutions with the model answer slide. Topics include bearings, averages, expanding and simplifying brackets, angle problems, transformations, proportion, simultaneous equations, similar shapes, indices, surds, circle theorems, algebraic fractions amongst other topics. Questions are from Edexcel past papers.
