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.

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.

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.

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

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.

Some easy questions as lesson starters. - Finding simple percentages, like 10% or 15% - Finding any percentage, like 23% or 92% - Finding percentage increases and decreases - Converting between fractions, percentages, decimals Answers included on the Power Point.

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.

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.

A series of examples and full solutions on the following topics - Volume of a Prism (cuboids, cylinders and triangular prisms) - Surface Area of a Prism (cuboids, cylinders and other prisms)

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 powerpoint-activity to learn and revise about vectors. There's been a robbery! Can you help Inspector Vector solve the crime by collecting clues? This is a fun activity for groups that includes: - adding and subtracting 2D and 3D vectors - finding the magnitude of 2D and 3D vectors - adding and subtracting vectors like a and b - some practice with surds for magnitude of vectors - visualizing vectors in 3D - using some logic to solve the crime Solutions to each clue included in the Power Point notes. Takes a very good class about 1 hour 30 minutes.

An introduction to Game Theory that I gave to a class of smart 16 year olds. Introduces the idea of a game, and gives some examples of simple two player games and up to zero sum games. Some fun examples of games you can play in class!

A worksheet with four pre-printed distance-time graphs for pupils to interpret. Their answers should be sentences such as "go at 4 metres per second for 3 seconds, then pause for 2 seconds, then ..."

A series of four worksheets to progressively introduce pupils to the idea of adding and subtracting fractions by matching the denominators. Rather than just presenting it to them as a rule, they work through simple examples to gain an understanding of what is happening. I wrote this out of frustration with a poor class who simply didn't seem to understand how fractions worked, and although they could memorise a method, would then misapply it (for example, trying to add three fractions with them was a disaster, until they actually understood what they were doing)

A two page Power Point with questions revising arcs and sectors.

A series of four worksheets about domain, range and composite functions. There is many lessons work here with lots of practice. The four parts are: - Domain and Range - Composite Functions - Further Functions (combining domain, range, composite) - Extension (proofs about linear functions) All provided with full solutions
