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...

I am about to tackle rearranging formulae (a topic so many find difficult) with my Year 10 class so came up with this in an attempt to make them more comfortable with playing with algebra; it should also encourage discussion about different ways of doing it.

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.

This is designed as a starter, plenary or a discussion exercise. There are four "explosions" to work through and I have given you the choice of the students working out the shapes from the properties or finding the properties given the shape. This moves from triangles and quadrilaterals to polygons to 3D shapes. Some shapes have the same property so link to the same cloud. This has been designed to check understanding and to give some the opportunity to expand on properties. I have not included all properties of all shapes to naturally generate discussion and differentiation.

Eight matching activities, getting increasingly difficult, on various different formulae to rearrange. These are designed as plenaries or starters and should encourage 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.

This is a set of 6 sheets of increasingly difficult simultaneous equations designed to make students think and discuss how to work through their solutions by giving them different parts of the process. They include simultaneous equations that involve a linear and a non-linear equation. This is also designed to stretch at GCSE or could be used at the start of A level.

Four matchings getting increasingly difficult at they go Firstly spot the correct formula for the correct triangle, the next two calculate a missing side and finally use Pythagoras to find the area of a shape. These have been designed to be used as starters or plenaries but you could use them as a main lesson activity; up to you.

There are eight matchings here: 4 surface area and 4 volume. They get increasingly difficult moving through cubes/cuboids to prisms to cones, cylinders, pyramids and spheres. These are designed to be used as starters or plenaries but you can use them for a lesson main activity, totally up to you.

This takes students through basic shapes (rectangles and triangles) to trapeziums and parallelograms and finally circles, including compound shapes. I use these as starters or plenaries but use them how you like.

A set of six spiders which encourage students to show every stage of their calculations as they tackle increasingly difficult questions. There are also some question where the answer is given and the workings shown so that students can work backwards; this is designed to avoid students getting stuck in a rut and not thinking about what they are doing in each case.

Six matching activities: 1 mode, 1 median, 1 mean, 1 mixture (all include frequency tables), 2 grouped data. These are designed to be starters or plenaries but could be used as a whole lesson activity if you wish.
