Prof Richard Wiseman recommends designs and images to promote creative thinking - show them on a screen or print them off as posters. Some illusions, some patterns, some simple tiling - not for discussing, just for being there. One set just slides, and one with an index page for choosing the desired image, and an index button on each slide. All images are mine, so no problem with copyright.

A PowerPoint demonstration of an early method of finding prime numbers. Plus some 100 grids to use with the activity.

Probability questions from a variety of past examination papers, suitably changed, and some new ones created to reflect the 2017 examination, with multiple choice answers added by me. Not yet trailed in the classroom so please advise me of any mistakes. (Nobody’s perfect, as Joe E Brown famously said on screen.)

Standard style lesson plans put into PowerPoint for easy showing in the classroom, printing for handouts etc. All the objectives covering Number, Probability, Statistics, and Ratio, proportion and rates of change included. Twenty seven lessons in all. All you have to do is add your own particular circumstances, resources etc. After getting a 'one star' rating for the paid set of thirty, I thought of this - try these three for free, and if you like them, you can buy the full set, which cost £1.

Standard style lesson plans put into PowerPoint for easy showing in the classroom, printing for handouts etc. Elsewhere on TES I have created twenty seven lessons in all, covering the rest of algebra, geometry and measure for higher tier. There is also another set covering number, ratio, proportion, and statistics and probability, and also three free samples of number. All you have to do is add your own particular circumstances, resources etc. After getting a 'one star' rating for the paid set of thirty, I thought of this - try these three for free, and if you like them, you can buy the rest of the set, which cost £1.

Multiple choice quiz for checking understanding at any stage. Simple area from KS2, but useful for revision at KS3.

Maths. Descriptors and specifications for UK Key Stage 4, although equally adequate for KS3. All lovingly put into word clouds using Wordle. I made B/W versions some time ago, but now I've been asked for colour, so here they are. Copyright on final images (c)Colin Billett 2015 And all credit to Wordle, as cited on the website: 'May I make money off of Wordle images? Yes. You may take a Wordle, put it on your book cover, your t-shirt, your campaign poster, what have you. You may get rich off it. If you want to give credit to wordle.net, feel free!' So again, all credit to wordle.net, and many thanks! Any problems, please let me know and I can change the formats.

A very short worksheet with four examples of price reductions - which one represents the greatest percentage discount? Alternately all on one slide of PowerPoint, plus the solutions on the same Powerpoint. Twenty minute activity, warm up, revision etc. (And I've corrected a mistake on the baguettes question and answer, I hope.)

Just the specifications for Maths KS3 put into Word, which you might find easy for cutting and pasting into lesson plans etc.

Two PowerPoint presentations for Key Stage 1, or KS2 revision. One gives the properties of shapes in terms of surfaces, faces, vertices, edges etc., with pictures, for naming. The other is a collection of photographs of real shapes to be identified. Accompanying worksheets for £1 on the premium resources. https://www.tes.com/teaching-resource/maths-3d-shapes-key-stage-1-or-key-stage-2-revision-bundle-of-fully-supported-activities-11180981 All images (c) Colin Billett 2015

Learners have so little practice of abstract reasoning in mathematics, and often confounded by what might seem to be simple questions right through the key stages. So I've made a one-sided set of questions just to give them a bit more experience.

Cards to assess understanding and generate discussion, with a PowerPoint version of the same cards for plenary.

A full set of resources to deliver the construction and interpretation of frequency polygons. Suitable for KS3, Foundation Tier GCSE and as a starter for Higher Tier before doing Cumulative Frequency Diagrams. Includes lesson plan, warm up starter activity on collecting data, PowerPoint on how to draw a frequency polygon, activities for the learners to undertake, and a plenary slide-show with suitable questions for checking learning. All data genuine and gathered this year.

Introduction to factors, multiples and prime numbers, with activities, worksheets, and SAT style questions for practise or assessment. Great for revision at KS3 or Foundation GCSE. Plenty to engage, and some more challenging questions. Mathematics Curriculum KS2 Year 5 Pupils should be taught to: • identify multiples and factors, including finding all factor pairs of a number, • know and use the vocabulary of prime numbers • establish whether a number up to 100 is prime and recall prime numbers up to 19 They use and understand the terms factor, multiple and prime, and square numbers. Year 6 • identify common factors, common multiples and prime numbers

Three sets of equations, all fairly simple linear and suitable for anyone from Year 6 upwards. Great for quick thinking, mental maths, abstract thinking, and reverse operations. And it might give you ideas for making some of your own. Better still - get the learners to make one using a camera/phone/scanner and PowerPoint or a simple slide show.

Everything you need for a lesson (or two) on reading and interpreting a cumulative frequency graph. Starter activity on PowerPoint to review average and range, with common mistakes and a more challenging question; a presentation in PowerPoint on reading and interpreting a cumulative frequency graph with two examples; learner activities, four questions in Word or PDF; a plenary presentation in PowerPoint to check learning; and a lesson plan to make the whole thing complete. Suitable for high achievers at KS3, or Higher Tier on GCSE now and for the 2015 specs. Can be uploaded to a VLE for the learners to follow themselves.

GCSE Mathematics - Foundation and Higher Tier. Finding the equation of a line through two points and perpendicular lines. A worksheet/activity that reminds learners of the algebraic form of a straight line, and goes on to finding the equation of a line joining two points and find the equations of perpendicular lines. Lots of GCSE style questions. Foundation Tier Plot graphs of equations that correspond to straight-line graphs in the coordinate plane; use the form y = mx + c to identify parallel lines; find the equation of the line through two given points or through one point with a given gradient. Higher Tier Plot graphs of equations that correspond to straight-line graphs in the coordinate plane; use the form y = mx + c to identify parallel and perpendicular lines; find the equation of the line through two given points or through one point with a given gradient.

Expanding Binomials and Factorising Quadratic Expressions Objectives: To be able to: • expand products of two binomials • factorise quadratic expressions of the form x2+ bx + c, including the difference of two squares All the research says that girls learn best by understanding, and that by far the best approach to expanding and factorising is by using the grid method. I’ve done this very successfully for years, and retention is greatly improved by giving as little input as possible, and giving the learners challenges to complete. Plus an investigation to give that stretch and challenge. A full set of resources for learning how to expand and factorise, with a PowerPoint that can be used for class discussion. Plus some extra exercises for homework or assessment in a subsequent lesson. And a reminder of multiplication and addition of positive and negative numbers for a quick warm-up. All answers included!

Forty six questions of general arithmetic in the style of UK SATs papers from 2000 onwards at KS2. The difficulty is deliberately spread through each of the two sections so that learners who find one question difficult can move on and still find accessible questions later. Great for revision at any time during the year, and quite appropriate for KS3 aiming for Foundation GCSE. In fact, good for any time when learners need a bit of practice on the sort of questions they will meet in exams and tests.
