Two simple multiple-choice quizzes covering addition and subtraction. The first is simple halves, quarters and eighths; the second covers halves, third, sixths, fifths and tenths. Aimed at year 5, but great for revision in year 6 before they search for common denominators. And good for KS3 and KS4 revision. Illustrated throughout, with answer slides after each question.

Fifty slides in a PowerPoint for class discussion of equivalent fractions leading to simple addition of fractions. Nothing complicated - made for class activity and discussion. Get the learners to answer on mini-whiteboards or simply answering each question. Fully illustrated, with answer pictures for each question, as well as repeat slides for the learners to come up with answers. And designed for working in the head of the learner rather than pencil and paper. (Too much time is often spent with pencils and not enough talking.)

National Curriculum Maths year 6, but also essential for revision in KS3, and great for lower tiers of Foundation GCSE. 'Multiply simple pairs of proper fractions, writing the answer in its simplest form'. Guidelines say: 'Pupils should use a variety of images to support their understanding of multiplication with fractions. This follows earlier work about fractions as operators (fractions of), as numbers, and as equal parts of objects, for example as parts of a rectangle.' Clear step-by-step presentation with questions and answers built in for class discussion and question/answer session. Everything for at least one lesson and some consolidation.

A full set of activities to engage the learners in finding the area of parallelograms and deriving methods and formulas. Good for practice or revision at any stage. Covers the specs for Year 6.

Maths GCSE Foundation & Higher. Surds & irrational numbers, three activities or investigations in shape and measure. Finding the length of a the side of a square that leads to an irrational number. Comparing ratios of paper sizes to derive the ratio of length to width for A4 paper. Finding the area and perimeter of the pieces of a tangram. All good stuff that leads the learner through different process to derive lengths and areas using surds, and to add and simplify with surds. Needs knowledge of Pythagoras, which is KS3. So great for revising Pythagoras with surds.

Two starter activities to introduce perimeter and area of simple rectangles and rectilinear shapes in KS2. Great for practice at any stage.

Developing area and perimeter to look at shapes with same areas but different perimeters, same perimeters but different areas, and equal area and perimeter. Engaging activities for the learners. Covers Year 5, but good for revision and practice at later stages.

Key Stage 3 mathematics specs: Standard Form KS3 • interpret and compare numbers in standard form A×10n, 1≤A Two sides of data, for positive and negative indices, of science data to change between ordinary numbers and standard form. Great for revision for GCSE classes. Answers included!

Some ideas for KS2 Geometry, covering part of the specs for Year 3. • recognise angles as a property of shape or a description of a turn • identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn; identify whether angles are greater than or less than a right angle • identify pairs of perpendicular and parallel lines. Editable in Word so you can remove the 'Year 3' reference in the headers - I do it for my own recognition. Hence suitable for revision in year 4 and above. Plus a presentation showing horizontal and vertical through photographs.

Area and perimeter at Key Stage 2, but also good for revision and practice at any stage. Questions in the style of SATs.

Full set of engaging activities to lead the learners to deriving methods and formulas for finding areas of triangles. Covers KS2 specs for Year 6, but good for revision and practice at any stage.

Questions culled and adapted from some very old papers, which means that none of the current learners will have seen these. Actually, very little changes, and although these are at the top end of the scale - some of the new ones may be even trickier, but these are great for getting the basics for Higher Tier.

Set of questions in the style of SATs for assessing or practising perimeter. Covers the requirements of Year 5 National Curriculum.

Questions culled and adapted from some very old papers, which means that none of the current learners will have seen these. Actually, very little changes, although these are the more basic end of the scale - some of the new ones may be trickier, but these are great for the lower grades.

Surds and and an understanding of irrational numbers are new to GCSE Foundation, so I’ve produced a clear and simple PowerPoint for classroom use to introduce the topic. Other stuff available on working with surds etc. I’ve added a pdf version to solve the problem of different versions of PowerPoint and some images not working well on ppt.

Big bundle of 10+ worksheets for telling the time and drawing hands on a clock face, meeting the curriculum for Year 2. Standards: ‘Tell and write the time to five minutes, including quarter past/to the hour and draw the hands on a clock face to show these times.’ Precision drawn clock faces in Word and PDF for the learners to read the times, and draw missing hands on the clock faces – minutes, hours, and both minutes and hours. Plus a few KS2 style simple clock questions.

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

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.

Clear and simple examples of constructions for KS3 and KS4, and loci questions for GCSE. An identical PowerPoint to the activity to talk the learners through the processes. All tried and tested, and successful with learners. Answers provided for learners to check their own solutions. All images (c)2015 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.
