There are four trees where students can work from bottom to top, choosing an appropriately challenging start point if they wish. This is “introduction to algebra” stuff, I will do expanding and factorising on a separate file but these could offer nice starters or plenaries. It contains adding/subtracting as well as multiplying variables and collecting like terms.

Find the appropriate equivalent fraction and find the punchline to Tim Vine’s joke; designed as a bit more practice for some of my Year 7 and 8 classes, but could be useful for others. I have uploaded PDF versions so those who don’t have Equation Editor can see them; no need to thank me…

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 an exercise in finding the best way of buying what a customer wants given four different “deals” on pricing. You can buy more than required but not less which should add an extra bit of challenge. Workings are essential and I have provided answers on a separate slide each time. There are five to work out and this should lead to nice mathematical discussions. I have also put this in a format that could be used easily online if this is desirable.

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.

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.

A task based on card shuffling from QI from a video posted on Twitter by @bobloch. What possible order could the cards be in in each case?

This is designed to help introduce factorising of quadratic equations in order to solve them. This should lead to some discussion.

Show it for 20 seconds then they have to remember it exactly. I put the picture of me on there so they would concentrate on their reproduction rather than staring around the room, but feel free to change it to a picture of your choice!

In this activity various cartoon characters have been transformed - can the students describe each transformation?

Choose one of the 6 options and then say what happens next when solving the equation. I used a template (with permission!) for the music from the excellent resource written by DanielBurke - check his resources out as they are top quality. The animations are little clunky, but do the job - I'm sure you could all make it look like Avatar! If you find the answers already on the slide then powerpoint has messed up the animations. Just contact me and I can send you my version.

The idea is Mr Barton's, but this is my probability contribution. Show for 30 seconds, they then get down what they can remember. Show a few times until they think they&'ve finished then check their against yours. Simples!

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 takes students through expanding a single bracket, factorising a single bracket, expanding two brackets and factorising quadratic expressions. Hopefully this should lead them in manageable steps to factorising quadratics, including a few with the coefficient of x squared being greater than 1. When I find errors I have corrected them...

This contains 4 solving equations activities of increasing difficulty. This encourages discussion and insists upon students showing their working.

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.

Five HCF and LCM functional questions using the characters from Phineas and Ferb. All put together in a PowerPoint and including answers. Now with a link to the Phineas and Ferb theme tune! Typos corrected.

This is designed to lead students through solving quadratic equations by completing the square from quite basic to difficult. The activity is also there to encourage discussion in class and helps them get into good habits regarding setting their solutions out.

Three spiders on transformations (both describing and drawing) that getting increasingly challenging from spider 1 to spider 3. Spider 1 contains reflections in the x and y axes, translations and rotations about the origin. Spider 2 contains reflections in horizontal and vertical lines (x=n or y=n), rotations around points away from the origin, and an enlargement. Spider 3 contains reflections in diagonal lines (y=-x), roattions away from the origin and fractional and negative enlargements where the centre is not the origin. They should encourage discussion and I hope the diagrams are large enough (they are as large as I can make them).

The aim of this is as a starter or plenary but could be used as a class activity. This activity is designed to get students thinking and discussing properties of number. The aim is to allow students to show what they do/don't know and understand. I have two versions: one where students find the number given the properties and vice versa which I suspect will create more discussion. There will be extra properties I've left out on purpose. There is a blank to make up your own too.
