Equal Parts Poster A simple and elegant demonstration of fractions as part of the whole. Fractions up to twelfths are shown in a variety of different shapes as divisions of a square. | This poster combines the methods of representing a fraction as a sector of a circle and as a proportion of a bar of constant length. In doing so it illustrates in an interesting and significant way the relationships between all proper fractions up to twelfths and their decimal equivalents. £3.53 (inc.VAT) |
Perimeter and Area The essential message of this brightly coloured poster is that the area of a shape and its perimeter should not be confused. It emphasises that a fixed area can have very different perimeters and a fixed perimeter can enclose very different areas. When teaching this important part of the mathematics curriculum, this poster offers useful support. £3.53 (inc.VAT) | ||||

Teaching and understanding fractions can be assisted by representing them visually as sectors of a circle, proportions of a strip or proportions of a square. This material from the USA is designed to use all three methods and illustrates in a physical form the relationships between proper fractions as far as twelfths. |  | |||||||||||||

Rainbow Manipulatives Made of a hard and precision-cut plastic material, these pieces illustrate the relationships between halves, thirds, quarters, fifths, sixths, eighths, twelfths and the whole as a square or as a circle. Each packs away into a box which also serves for storage and as a work tray. | This pack of 52 cards treats each of 13 simple fractions in four different ways: as numbers, as words, as parts of a circle and as parts of a square. The cards can be arranged, sorted and grouped to help to relate the concept of a fraction to the symbols, words and images which represent them. £3.53 (inc.VAT) | |||||||||||||
