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.

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!

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.

From drawing the next pattern to finding the nth term of an arithmetic sequence. Enjoy!

I've recently discovered this in my folders on my computer. It is a 10 question non-calculator quiz using real situations.

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 deals with plotting co-ordinates up through gradients and equations of lines, to plotting different types of graph and finally transforming functions.

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).

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 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 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.

I just wanted something that covers bar graph; this covers “normal”, comparative and composite bar graphs and is designed, in two cases at least, to create discussion.

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.

This powerpoint is for classes to do in teams. Each summer related question takes 30 seconds to answer (an alarm goes off and the link to the answer appears). There are 5 topics areas: Number, Algebra, Shape & Space, Data Handling, Pot Luck. Each topic has 5 questions worth a different amount of points based upon difficulty.

Tutorial with questions taking you through primes, multiples, writing and reading numbers, directed numbers (negative numbers), prime factors, HCF and LCM.

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.

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.

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.
