A great way to introduce formulas, with a fun activity to estimate how fast your reaction time is. The Power Point introduces the idea of reaction time then shows pupils a simple experiment they can do, which leads to a formula for converting centimetres on a ruler to reaction time in seconds.

Seven christmas themed questions on the following topics: adding fractions, angles in triangles, dividing with fractions, substitution, negative numbers

A fun presentation for pupils to try and guess what each magnified image is. Can also be used in a more advanced way to try and work out the (length) and (area) scale factors between the original picture and the answer.

A series of nicely presented questions each with some money coming in and some expenses. It's quite simple but gives pupils plenty of practice dealing with the terminology and some simple numeracy.

A one page Powerpoint using 3D coordinates to introduce how to find the distance from one corner to the opposite in a cuboid.

An interactive Who Wants to Be a Millionaire game focused on numeracy questions. The questions near the end get very tricky! They are on the following topics - percentage, area, ratio, factorising, probability, volume, negative numbers, difference of squares, scale factors, angles, sequences, DST I normally do this with pupils writing their letters on mini-whiteboards before the right answer is displayed, and you can also do something with the lifelines if you like.

A worksheet of practice questions on everything to do with Higher Functions. domain and range max value of a function inverse functions tangent to a function showing a function is always positive sketch of a function differentiating a function quadratic inequalities

A write-on worksheet with 18 short questions revising exact values of trigonometry, Most questions simple e.g. sin(60) and also includes angles above 90 degrees, radians and a few questions on inverse trig. Solutions at the end.

A powerpoint with one question - exploring why going from 20 to 25 is not the same as going from 25 to 20.

A selection of questions (with full solutions) each asking 'how many ways' can something happen. Begins with simple problems that are small enough that they can be done without any special technique, then problems that require the 'multiplication principle' then on to permutations and combinations.

A series of extension projects about counting. Each question is a seemingly simple problem that introduces pupils to combinatorics. For example: - how many ways can you make change for a pound? - how many four digit numbers have digits that sum to 9?

A fun lesson with shapes for pupils to cut out and reform. Everyone should have fun with this. Although even young children can understand dissection it hides complicated mathematics in geometry in proof. The dissections to try here are: - A rectangle into a square with one cut - A vase into a square - An equilateral triangle into a square - A 8 by 8 square into a 13 by 5 rectangle (!) - A couple of miscellaneous shapes - An approximate dissection of a circle into a square

A rare chance to see the first ever use of an equals sign "for what could be more equal than two parallel lines" and therefore the first ever equation. Pupils can read the Olde English, translate it into modern equations, then solve them. The first two are linear, the remaining four quadratic. Provided with full solutions.

This is to introduce pupils to decimals, using a context they are probably already familiar with (the time to run the 100 metres). Pupils work in pairs to complete some exercises looking up times, then get familiar with a stopwatch, then compare some decimal times.

The key to exam technique in mathematics is to solve each problem multiple times, using independent methods. You also want an independent check. Mathematicians hate to get things wrong! This presentation and activities will help your students from making mistakes.

What do you do when there's not enough information to solve a problem - or too much? This presentation and activities aims to teach pupils how to handle more difficult problems when it's not clear what to do. There are multiple examples from algebra, geometry and trigonometry.

A presentation and questions for pupils to consider what makes maths problems hard? They will then be better equipped to solve (and create) their own problems. The main way that problems are made more difficult are: - Make the numbers harder - Repeated application - Difficult vocabulary - Extra operation at start or end - Reverse the problem - Hide information in a story - Extraneous information

A fascinating activity encouraging pupils to think about 'Fixed Points', things that stay the same when there is a change. For example, in the doubling function 0 is a fixed point as doubling keeps it the same. These fixed points have surprising applications, including the amazing result that if you scrunch up one piece of paper and put it on top of a flat identical piece, at least one point is in the same place! Pupils are guided along with a presentation with things for them to think about along the way. Some of the language is GCSE level but the ideas are applicable for all ages.

A short Powerpoint on common confusions such as 6 and 0, s and 5, ( and c and so on. Pupils are made aware of the pitfalls, and given tips for how to avoid them.

A series of examples and questions on the following topics: Express a change in value as Percentage Calculate Compound Interest Reverse Percentage Change Appreciation/Depreciation by a Percentage Provided with solutions
