Starting at the very beginning with numbers and counting, this book gently and reliably guides children and parents through the essential math concepts needed in the first few years at school. Readers can use it as a dip-in dictionary or work through by subject to build up knowledge and skills step-by-step.

Helped with bright illustrations, each concept is explained alongside worked examples of alternative methods as well as hints and tips for shortcuts and strategies. Ages 7+.

Illustrations and simple definitions covering such areas as number sense and operations, algebra, basic geometry, and data representation.

The Oxford First Illustrated Dictionary, beautifully illustrated by well-known picture book artist Emma Chichester Clark, is the perfect first building block for 5-7 year-olds to engage with words and language. Over 2000 entries give clear meanings and definitions, parts of speech, word forms, word families, synonyms and opposites to build vocabulary and first literacy skills. Not just a dictionary, this unique book brings to life the world of fairy tales, nursery rhymes, and picture books that children love. Winnie the Pooh and Georgie Porgie appear alongside Aladdin and Cinderella in the innovative example sentences. Rhyming words, little words hiding in big words, and riddles provide plenty of opportunities for fun word play, along with amusing word jokes and child-friendly word origins. The entry for 'crocodile' tells the child that the word comes from a Greek word meaning 'lizard' and ends with the joke: 'What's a crocodile's favourite game? Snap.'This wealth of information and fun with words is presented in a contemporary, easy-to-use, engaging layout, creating the most accessible and affordable dictionary and gift-book combination, the perfect buy for Christmas and holidays as well as for everyday use.

Authoritative and reliable, this A-Z provides jargon-free definitions for even the most technical mathematical terms. With over 3,000 entries ranging from Achilles paradox to zero matrix, it covers all commonly encountered terms and concepts from pure and applied mathematics and statistics, for example, linear algebra, optimisation, nonlinear equations, and differential equations. In addition, there are entries on major mathematicians and on topics of more general interest, such as fractals, game theory, and chaos. Using graphs, diagrams, and charts to render definitions as comprehensible as possible, entries are clear and accessible. Almost 200 new entries have been added to this edition, including terms such as arrow paradox, nested set, and symbolic logic. Useful appendices follow the A-Z dictionary and include lists of Nobel Prize winners and Fields' medallists, Greek letters, formulae, and tables of inequalities, moments of inertia, Roman numerals, a geometry summary, additional trigonometric values of special angles, and many more. This edition contains recommended web links, which are accessible and kept up to date via the Dictionary of Mathematics companion website. Fully revised and updated in line with curriculum and degree requirements, this dictionary is indispensable for students and teachers of mathematics, and for anyone encountering mathematics in the workplace.
