Big bundle of worksheets/activities to revise or practise trigonometry of right angled triangles, with Pythagoras and sin, cos and tan for finding lengths of sides or angles. In Word or PDF. Great for homework or assessment of learning in the classroom. Now on KS3 but always needs revising in KS4, especially on the new GCSE 9-1 specifications. • apply Pythagoras’ Theorem and trigonometric ratios to find angles and lengths in right- angled triangles

Everything you need for a lesson (or two) on creating, reading and interpreting histograms. Starter activity on PowerPoint on finding the areas of rectangles drawn on a co-ordinate grid, and finding missing lengths; a presentation in PowerPoint on creating, reading and interpreting a histogram with three examples, with equal class intervals and unequal class intervals; learner activities, with 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 at GCSE now and for the 2015 specs. Can be uploaded to a VLE for the learners to follow themselves.

Simple poster illustrating symmetrical, negative and positive skew. For display or for learner's reference. In Word or PDF, plus original spreadsheet file for playing with.

Everything for introducing negative numbers in KS2, especially for Year 4 but great for revision in Year 5 or above. PowerPoint to move on from counting numbers, adding zero and negative numbers. Lots of opportunity for open questions and direct questioning. PowerPoint includes ten questions for the learners to do as a group or individually. Powerpoint also given as a PDF so that it will open on any system, and look the same. Worksheet covers the specs - counting through zero, done on number lines presented in a variety of ways. Plus games to give the learners colourful, active and kinaesthetic learning. Year 4 programme of study Number – number and place value Statutory requirements Pupils should be taught to count backwards through zero to include negative numbers Year 5 programme of study Number – number and place value Statutory requirements Pupils should be taught to: interpret negative numbers in context, count forwards and backwards with positive and negative whole numbers, including through zero Images © Colin Billett

Simple reflection to introduce the concept. A dozen butterflies to sort, and half a dozen for the learners to make their own symmetrical butterflies. And two sides of square shading shapes to complete. Plus a second set with assorted shapes to complete. Year 4 • identify lines of symmetry in 2-D shapes presented in different orientations • complete a simple symmetric figure with respect to a specific line of symmetry. Pupils draw symmetric patterns using a variety of media to become familiar with different orientations of lines of symmetry; and recognise line symmetry in a variety of diagrams, including where the line of symmetry does not dissect the original shape.

Real life data to give the learners lots of practice using standard form. Easy conversion exercises leading to questions requiring calculation. All suitable for the current KS3 specs as well as solid revision and practice for GCSE. Standard Form KS3 • interpret and compare numbers in standard form A×10n, 1≤A GCSE calculate with and interpret standard form A × 10n, where 1 ≤ A < 10 and n is an integer

Mathematics Key Stage 2 Year 6: use negative numbers in context, and calculate intervals across zero solve number and practical problems that involve all of the above. Everything you need to introduce the next stage, and give learners plenty of practice.

Maths Key Stage 3 Standard Form: • interpret and compare numbers in standard form A×10n, 1≤A Four sides of questions ranging from simple conversion between ordinary numbers and standard form, to harder ones that require the application of assorted KS3 knowledge. Great for revision at GCSE.

Presentation with 52 slides and around fifty questions covering basic concepts of percentages, including fractional and decimal equivalents. Simple questions to develop fluency, misconceptions to correct, simple applications and written problems. Each slide followed by solution slide. Plus a clone of the questions in Word and as a PDF for further practise. So around 100 questions in total, with plenty of repetition and plenty of new questions slotted in. Plus answers for printing or otherwise. Originally produced for Functional Skills Levels 1 & 2 but entirely suitable for other groups. Easily editable into four different lessons for revisiting at a later date.

‘Tell and write the time from an analogue clock, including using Roman numerals from I to XII.’ Powerpoint introduction with lots of questions and handout, worksheets in Word and pdf, plus lots of real examples of clock faces. All you need to give the learners an initial experience, with recap and reviews.

KS1 programme of study in Word for easy cutting and pasting into schemes of work, lesson plans etc. Plus a table format for recording.

I use these to assess understanding, as well as for generating discussion. Foundation GCSE or Functional Skills.

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.
