Willams Kenneth. Vedic mathematics. Teacher's manual. Elementary level

Inspiration Books, 2009. — ISBN: 978-1-902517-16-2.This Manual is the first of three self-contained Manuals (Elementary, Intermediate and Advanced) which are designed for adults with a basic
understanding of mathematics to learn or teach the Vedic system. So teachers could use it to learn Vedic Mathematics, though it is not suitable as a text for children (for that the Cosmic Calculator Course is recommended). Or it could be used to teach a course on Vedic Mathematics. This Manual is suitable for teachers of children in grades 3 to 7. The sixteen lessons of this course are based on a series of one week summer
courses given at Oxford University by the author to Swedish mathematics teachers between 1990 and 1995. Those courses were quite intensive consisting of eighteen, one and a half hour, lessons. All techniques are fully explained and proofs are given where appropriate, the relevant Sutras are indicated throughout (these are listed at the end of the Manual) and, for convenience, answers are given after each exercise. Cross-
references are given showing what alternative topics may be continued with at certain points. It should also be noted that in the Vedic system a mental approach is preferred so we always encourage students to work mentally as long as it is comfortable. In the Cosmic Calculator Course pupils are given a short mental test at the start of most or all lessons, which makes a good start to the lesson, revises previous
work and introduces some of the ideas needed in the current lesson. In the Cosmic Calculator course there are also many games that help to establish and promote confidence in using the Vedic system. Some topics will be found to be missing in this text: for example, there is no
section on area, only a brief mention. This is because the actual methods are the same as currently taught so that the only difference would be to give the relevant Sutra(s)
