A Maths Dictionary that does exactly what it should do!, 8 Sep 2004
'128 pages - contains over 600 words in alphabetical order, each with an easy-to-understand meaning. The words are drawn from the words used in primary school mathematics teaching, along with maths words that are in common everyday use. Where a word has several meanings, all are given. Explanatory pictures and diagrams help make the meanings of entries clear.' This dictionary stood out from the rest for our testers in KS 2, age 7-11 years. For the younger group it sorted out the 'am and pm' dilemma and helped them to understand the terms 'AD and BC'. Colourful graphs show eg 'Grouped Data, Bar Charts, Bar-Line Graphs, Block Graphs, Pictograms, Pie Charts etc, which helped older children with data handling and presentation exercises. Each word has a description then a 'keyword indicator box', for additional information e.g.:- 'ANGLE'- 'An angle is an amount of a turn. Angles can be measured in degrees' Two clear diagrams illustrate this and the keywords point to supplementary sections of:- acute angle, degree, obtuse angle, right angle, vertex. At the top age end it still presents as an informative book which is easy to grab and look up, like a well-thumbed reference book should be! Try this one for example - 'Eratosthenes Sieve'(an early method of identifying 'prime numbers', founded by the Greek mathematician, Eratosthenes who lived between 275 and 195BC)! An apparatus section, followed by information sections/tables further enhance the book which is completed by a comprehensive index. Money well spent!
