This is an investigation for the whole class to do at the same time, investigating the seemingly simple idea of the four corners of a rectangle. It will force pupils to get out of the simple thinking that every rectangle has to be lined up with the co-ordinate axes, with a horizontal base and vertical sides. Full solutions included.

Two pages of tricky riddles, that will keep pupils busy. The second page is much harder than the first. Solutions provided.

Pupils learn about money and get the chance to design their own coins. This activity is inspired by the Scottish Independence Referendum of 2014.

Practice multiplying and dividing - first of all 10, 100, 1000 etc. - then by 20, 300, 4000 etc. - then using decimals, e.g. 1.3 x 300 A series of worksheets revising these basic skills. Full solutions included.

This is a set of six puzzles presented as large scale Power Points. I used them as colour A3 posters for a monthly maths competition. These puzzles are challenging and give the scope for comprehensive answers. Full solutions included.

This is two worksheets practising some important basic skills. The first worksheet is powers of ten and multiplication. The second worksheet introduces two-step multiplication (e.g. multiplying by 20 is ×2 and ×10) and division. Full solutions included.

A whole class activity to practise basic skills of adding and subtracting, multiplying and dividing. Three different difficulties.

These two activities extend from 3 by 3 to 4 by 4 magic squares. Pupils design an individual magic square then search for symmetries.

A series of worksheets covering all aspect of rounding. - money, rounding to the nearest dollar/kilogram/penny - rounding to the nearest 10,100,1000 - using rounding to approximate answers - using rounding to approximate on more difficult problems Full solutions provided to worksheets.

A fun introduction to units, converting between e.g. metres and centimetres. A starter activity, two pages of worksheet activities, and a challenge to find the amount of air in the room.

This is a series of worksheets all about finding the area of 2D shapes (quadrilaterals and circles). - Recognising and naming 2D shapes - Knowing their properties - Knowing the formulas for their areas - Being able to calculate the areas

A worksheets investigating different coins, and using them to add up to different amounts. Starts easy, then challenging at the end. Full solutions included. Now includes a Power Point, which revises lots of the same skills.

Four sets of revision questions, with full solutions provided. • Algebra – equations • Algebra – brackets • Straight Line • Circles – angles • Circles – sector and arc length • Circles – Pythagoras • Pythagoras • Simultaneous Equations • Similarity • Volume • Parabola – Complete Square • Parabola – Factorise • Parabola – Quadratic Formula

A short Power Point explaining what VAT is, what you have to pay it on, and finishing with a question about Jaffa Cakes. Answers included on the Power Point.

A series of projects on rearranging formulas. (Note: Some of the embedded equations do not display well on the TES preview but they all display perfectly on the downloadable PDFs) Each project is linked to real life situations, and also includes lots of practice at other 9th Grade / 10th Grade Skills: standard form, algebra using brackets, volume formulas, rounding, units, surds .

Bridge is a card game that is great for teamwork and developing logical thinking. There are proven benefits to cognitive skills for children and adults. For more about the benefits see the attached 'What is Bridge' PDF. This is a set of resources for a school bridge club, or anyone wanting to learn more. It starts with Whist and Minibridge and goes all the way through to basic bidding:

A PowerPoint with two real-life examples of Hire Purchase questions.

This is an investigation into the different uses of stones and pounds (UK), pounds (USA) and kilograms (Europe) for weighing people. By the end pupils should be able to convert between the units effectively. Skills used: - Mental arithmetic - Converting between units - Rounding (the conversion numbers are approximate only) Full solutions provided on the Power Points.

Proofs of some of the key formulas in Advanced Higher Statistics. Not required for the course but some pupils (and teachers) may find it interesting. proof the two ways of writing the variance formula are equivalent proof that using the ‘divide by n-1’ formula gives the best estimate of a population variance proof of Bayes Theorem proof of laws of expectation and variance proof of the origin of the Poisson formula, and of the mean and variance proof of mean and variance for uniform discrete proof of mean and variance for uniform continuous proof that using proportions and the normal approximation to a binomial are equivalent proof a line of best fit goes through the average point proof the line of best fit gives the least squares proof of SSR formula proof in bivariate analysis DF=n-2 proof test slope parameter nonzero and coefficient of correlation nonzero are equivalent
