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.)

Simple PowerPoint presentation with twelve clock faces to share and discus in the classroom. A full set of ten worksheets to use with this is available for £1 at: https://www.tes.com/teaching-resource/maths-ks1-year-2-time-bundle-of-worksheets-for-telling-the-time-and-drawing-hands-on-a-clock-face-11184919

Statistics 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. Great for all sorts of things, and easily cut and pasted into shorter versions. Answers to follow, but shouldn't be too difficult to work out.

A set of questions challenging learners to apply knowledge of coordinates, and do some algebraic thinking.

Psychologists suggest that a distraction, using a different part of the brain perhaps, helps the problem solving process. Four sets, which you might not want to do all at once. Answer slides included.

Very simple algebra equations from photographs of onions. I took lots of photos of fruit and veg and now I'm wondering how to incorporate them into my learning experiences. This is the first attempt - find the value of the letter to solve the simple equation. Two sets, which can be shown on a screen or printed as slide handouts.

Rainbow coloured circle timer - lasts about a minute, but don't rely on accuracy. Pretty!

Simple set of cards, operations, and some simple challenges.

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.

Final batch of nine worksheets in the style of test questions, arranged by topics, covering rounding-off to units of measure. In Word if you want to cut and paste, or PDF if you want to print them as they stand. Good for revision and assessment. You will find the first two set of worksheets on TES, this is the last. Hope they prove useful.

Genuine modular paper questions which were popular in Word and now I've added them in PowerPoint. Around twelve questions to each test/quiz.

Another batch of ten worksheets in the style of test questions, arranged by topics, covering the topics Inequalities to Reading Tables. In Word if you want to cut and paste, or PDF if you want to print them as they stand. Good for revision at higher levels. You will find the first ten worksheets on TES, and the third batch of nine worksheets are also on TES.

Batch of ten worksheets in the style of test questions in Word and PDF. Topics A through to G. Look out for batches two and three. Great for lots of things, and very popular.

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.)

A simple little activity that can get the learners thinking - no more than a warm up. Ask the question, and show the second screen. You don't need to face the screen, just know the position of the cards. A learner tells you which cards (first, second, third etc.) contain the date of their birth. The rest is the puzzle!

Thirteen assembled images that lead to the name of football teams. You don't need to know anything about football. Use for ice-breaker, or just a bit of fun.

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.

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. You'll find the rest of the files here: https://www.tes.com/teaching-resource/ks4-gcse-higher-tier-specifications-and-objectives-30-lesson-plans-in-powerpoint-set-1-11126041

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