A one page sheet with eight common shapes on. Pupils should cut these out and physically fold them, to see which ones have lines of symmetry. I came up with this in response to pupils who consistently thought that a parallelogram had two lines of symmetry, and a non-square rectangle had four lines of symmetry.

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.

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 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.

Two pages of simplification, beginning easy (finding fractions equivalent to 1/2) and building up to more difficult questions (simplify 14/49). The aim is to highlight the similarity between finding equivalent fractions and simplifying, so pupils will recognise that they are really the same thing. Good for lower ability classes.

Three standard questions testing pupils can correctly use the Wilxocon test, for determining if there is a difference between two sets of data. There are also two extension questions. Provided with full solutions.

A financial activity to design your own bedroom and pay for it. You will need something like the Argos Catalogue (or IKEA catalogue) to use.

A series of five activities to help you learn how to use Excel, with an emphasis on mathematical formulae. The skills learned are: - using formulas (like mean, maximum etc.) - plotting graphs - colour coding cells

A set of five challenging questions testing the link between length, area, and volume scale factor. Full solutions provided. These questions were created by my pupils, so have a relatively real life context!

A series of statistics questions that cover everything that might be needed for an Advanced Higher Geography project. Largely overlaps with Advanced Higher Statistics. Topics included are: Descriptive statistics (mean, median, mode, range, interquartile range, standard deviation, standard error, coefficient of variation) Inferential statistics (chi-squared) Linear regression Nearest Neighbour analysis Full solutions at the end.

Mixed percentage questions, on these topics - percentage change - repeated percentage increase or decrease - reverse percentage

A series of ten questions asking pupils to prove Trig Identities. For example Show that 3 tan⁡x cos⁡x=3 sin⁡x All included with full solutions.

A worksheet with explanations then questions on radians. Includes converting to and from degrees.

A Powerpoint of Pythagoras questions covering the following topics: Squaring and square rooting Solving the equations that result from Pythagoras equations Finding long and short sides on triangles(with and without a calculator) ‘Double Pythagoras’ with two applications 3D Pythagoras with a space diagonal Distance between co-ordinates Converse of Pythagoras Answers at the bottom of each slide

Two sets of questions (non-calculator and calculator) practicing Fractions -equivalent adding, subtracting, dividing, multiplying Order of Operations Highest common factor Prime factorisation Expressing as a percentage and finding a percentage Square roots, and cube roots and squaring Algebra - solving simple equations, simplifying, substitution Rounding to one decimal place Answers provided too.

Nine provocative questions to get pupils thinking about infinity. Each one has footnotes on the Powerpoint to guide towards the answer. What are Zeno’s paradoxes? Is 0.9999999999999999999… the same as 1? What is the smallest decimal number more than 3? What is infinity plus one? What is Hilbert’s Hotel? If something is true for the first million numbers, is it true for all the numbers? What is 1 – 1 + 1 – 1 + 1 – 1 … equal to? Are some infinities bigger than others? Are there more: numbers, fractions, or decimals?

A worksheet with five real-life problems that require using very big or very small numbers - How far does the Earth travel in one second - How many Earth's fit in the sun - How long does it take for the Sun's light to reach us - How long does it take to get a radio signal to Mars - How many atoms are in the Earth These require a bit of other basic mathematical knowledge (e.g. area of circle) but mostly pupils are lead through each problem in stages. Full solutions included at the end.

Worked examples and questions on these four topics: Substitute values into expressions and evaluate Multiply two brackets Solve inequalities Create and solve inequalities for problems in words Solutions included

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

A simple powerpoint with a shop where items cost different amounts. You then ask the pupils how much change they get from a pound. Easily adaptable to add your own items (or change the existing prices) or extend by asking about buying multiple items, starting with £5 etc. Aimed at CfE Level 1 Mathematics
