The Circle Poster A circle is easy for children to recognise, but how many realise just what a unique and special shape it is? This poster draws attention to the properties of the circle in a colourful and imaginative way and introduces the necessary vocabulary. Three panels illustrate angle properties related to a circle, the relationship of the circumference and area to pi and some different approximations to the value of pi. £3.53 (inc. VAT) |
Exploring the Triangle This poster presents the properties of the triangle in a colourful and thought- provoking way. It shows acute, right and obtuse angled triangles and how the bisectors and perpendiculars meet at four special centres whatever the shape of the triangle. How these centres relate to the Euler line, the circumcircle, the incircle, the excircles and the nine-point circle is also shown as well as triangles where the sides and angles have special relationships. £3.53 (inc. VAT) |
Looking at Quadrilaterals This poster is a colourful statement of properties which are shared by all quadrilaterals and also the special properties of the eight quadrilaterals with special names such as ‘square’, ‘rhombus’, ‘kite’, ‘parallelogram’ etc. There is also a quiz asking for these special quadrilaterals to be grouped according their properties. £3.53 (inc. VAT) | ||||

Magic Squares Poster “Magic squares are a visible and magical demonstration of fundamental order in the structure of numbers, not just simple puzzles to be solved by trial and error.” This poster illustrates this premise in a colourful way and shows some of the most remarkable magic squares so far discovered. £3.53 (inc. VAT) |
Quadrilaterals & Polygons Posters A square wheeled bicycle or a rhombus shaped house? Both seem equally unlikely but this pair of posters offers an original and light hearted way of learning the names and recognising the shapes of quadrilaterals and regular polygons. Very colourful and attractive. £3.53 (inc. VAT) | |||

The Power of Coordinates It was René Descartes who first had the idea of how to relate algebra to geometry and who invented the concept of ordered pairs and coordinates. This poster illustrates a variety of ways in which different kinds of coordinates can be used and how they are related to each other. Whether they be in two, three, four or more dimensions, be imaginary or real or serve as grid references to locations on land or in the sky, the power of coordinates to help clarify mathematical thinking is clearly evident. £3.53 (inc. VAT) |
Number Patterns Poster A vivid presentation in poster form of some remarkable addition, subtraction, multiplication and division sums. Each of the chosen calculations generates a distinctive number pattern or relationship. There are curious repetitions of digits and the reappearance of the same numbers over and over again at different stages in similar sums. A fine way to raise consciousness of the mystery and delight of numbers. |
Factors: Primes & Pairs The first one hundred integers are displayed on this colourful poster in the form of a powerful spiral of linked circles. Designed by Magdalen Bear, it shows all their prime factors with each prime number being represented by a different colour. It is interesting to identify numbers on the spiral by their prime factors and to confirm them by using those of their neighbours. Also there is a table which shows all the pairs of factors which make up each number. This poster makes an original contribution to work on factors and on prime numbers. | ||||

The Theorem of Pythagoras Poster Taking literally the statement about the squares on the hypotenuse and the other two sides, this poster illustrates the well known theorem in a colourful and instructive way. It also shows a simple trigonometrical proof and draws attention to the special sets of numbers known as Pythagorean triples. There is also a nice pointer to other geometrical representations of the theorem. |
The Golden Ratio Down through the ages, the special ratio which is known as the golden ratio, the golden proportion or the divine proportion has had an important place in art, architecture and music. It also has been discovered to occur naturally in giant sunflowers. In mathematics, this ratio is strongly related to the proportions of the terms of the Fibonacci sequence and it can easily be proved to be a root of a simple quadratic equation. It is also to be found to be a fundamental ratio in regular pentagons and polyhedra and can be calculated to any required number of decimal places. £3.53 (inc. VAT) |
Fibonacci Numbers 'Fibonacci' numbers are named after the Italian medieval mathematician who first posed a rather artificial problem about rabbits. The answer to this puzzle was a sequence of numbers which was soon discovered to be very special and which occurred in many real situations concerning plants and animals. The best known situation is the one concerning the numbers of spirals to be found on flower seed heads and on the cones of pine trees. The poster includes a wide variety of different situations where Fibonacci Numbers occur and serves as a stimulating introduction to them and their properties. £3.53(inc. VAT) | ||||

Fermat’s Last Theorem This highly readable account of the background to the recent proof of Fermat’s Last Theorem was developed and inspired by Simon Singh after his work on the BBC Horizon documentary. Book £7.99 |
Fermat’s Last Theorem This poster tells the story of one of the most exciting quests in the whole of mathematical history. £3.53 (inc. VAT) |
Euler's Theorem Poster The famous theorem connecting the faces, edges and vertices of polyhedra is treated in a very colourful way in this poster. It combines explanation and proof with some puzzle diagrams and suggestions for investigations. £3.53 (inc. VAT) | ||||
