The Cosmic Calculator - 5 Volume Set
by Kenneth Williams and Mark Gaskell

The remarkable system of Vedic mathematics was created after careful study of ancient Sanskrit texts early last century. The Vedic system with its direct, easy and flexible approach forms a complete system of mental mathematics (though the methods can also be written down) and brings out the naturally coherent and unified structure of mathematics. Many of the features and techniques of this unique system are truly amazing in their efficiency and originality.

Being a mental system, Vedic Mathematics encourages creativity and innovation. Mental mathematics increases mental agility, improves memory, the ability to hold ideas in the mind and promoter confidence, as well as being of great practical use.

Best suited for teacher’s use in a classroom setting with guide & answers in separate volume. Written for 11-14 year old pupils (some of the material in Books 1 and 2 is suitable for children from the age of about eight) this course covers the National Curriculum for England and Wales. The full course consists of three Textbooks, one Teacher's Guide and one Answer Book for all 3 volumes.

THE TEXT BOOKS Each of the three books has 27 chapters each of which is prefaced by an inspiring quote from a famous mathematician, philosopher etc. Also in each book there are historical notes which relate to the authors of the quotes, a list of Sutras and three other short but interesting sections (e.g. Pascal's Triangle, Fractals).

Book 1 deals mainly with basic arithmetic, proportion, decimals, basic algebra and geometry, polygons, area, volume etc. Book 2 extends this, covering fractions, probability, sequences, negative numbers, percentages, equations, graphs, charts, transformations, bearings etc. Book 3 develops this further into recurring decimals, square and cube roots, division, divisibility, the musical scale, formulae, simultaneous equations, quadratic equations, proof, similar triangles, area of a circle, nets, conic sections, loci, motion, vectors, Pythagoras' theorem, triples, coordinate geometry etc.

THE TEACHER'S GUIDE Contains A Summary of the book. A copy of the Unified Field Chart for that book. Notes on the content of the chapters- advice, suggestions etc. Mental Tests (correlated with the books) and answers- which allow earlier work to be regularly revised, give stimulating ideas relevant to the current lesson and which develop themes from earlier tests which may ultimately become the subject of a lesson. Extension Material and answers (about 16 per book)- these consist of a 1 or 2-sided sheet given to children who work fast and get ahead of the rest of the class. Many of these are also very suitable for work with a whole class. Revision Tests and Answers- There is a revision test every 4 or 5 chapters. This includes a mental test of 10 questions. Games, Worksheets etc.

THE ANSWER BOOK This contains answers to all exercises and other numbered questions in the text and should be available for pupils during lessons.
