The Soroban: Construction and Use of the Japanese Abacus introduces and explains the basics of building and using a soroban for addition, subtraction, multiplication, and division problems. The text includes detailed building plans and step-by-step instructions - with numerous examples - for performing calculations. Use of the soroban for routine mathematical calculations enhances student understandings of place-value, the concept of borrowing in subtraction problems, and that of carrying in addition problems. Soroban use also strengthens fluency with multiplication and division tables and with mental calculations. Building and learning to use the soroban is an engaging hands-on project, well suited for mathematics classrooms from grades 4 to 7.

I am happy to present this book to the students who wish to learn abacus and wish to appear in the objective type competitive examination. In such examinations, the students are required to solve the problems in limited time. The conventional method of solving the mathematical problems in not only time consuming but also prone to mistakes because of lengthy methods involved. This book explains the short cut method through abacus and integrating approach of Vedic mathematics method and abacus method of solving the problems in faster way. For the convenience of students and easy understanding, the basic approach of abacus is divided various chapters of learning and each chapters are again divided in to various steps. This book covers basic terminology of abacus, formulae in abacus and their applications in performing the basic operations of mathematics, including additions, subtractions, multiplications and division. Each chapter contains rules, formulae, examples of solution with step by step approach and exercises for practices.

The Creative Enterprise of Mathematics Teaching Research presents the results and methodology of work of the teaching-research community of practice of the Bronx (TR Team of the Bronx). It has a twofold aim of impacting both teachers of Mathematics and researchers in Mathematics Education. This volume can be used by teachers of mathematics who want to use research to reflect upon and to improve their teaching craft, as well as by researchers who are interested in uncovering riches of classroom learning/teaching for research investigations. This book represents the results of a collaboration of instructors discussing their own instruction research, analyzed through a conceptual framework obtained via the synthesis of creativity research and educational learning theories, based upon the work of Piaget and Vygotsky. The editors see an urgent need for creative synthesis of research and teaching, an example of which is presented in the book. Two central themes of the book are the methodology of TR/NYCity model and creativity, more precisely, creativity of the Aha moment formulated by Arthur Koestler (1964) in a very profound but little known theory of bisociation exposed in his work “The Act of Creation”. Incorporation of the theory of bisociation into classroom teaching of mathematics provides the key to enable students who may struggle with mathematics to engage their own creativity, become involved in their learning process and thus reach their full potential of excellence. Creativity in teaching remedial mathematics is teaching gifted students how to access their own giftedness.

Carried out over a period of ten years, this is a listing of scientific instruments dating before 1920, preserved in many collections throughout the island of Ireland. It gives location, date, and description for each of the more than 5,000 entries, together, where appropriate, with relevant accompanying detail. It demonstrates clearly that Ireland has an important resource which hitherto had not been appreciated. It also preserves information about collections which have since been lost, sold, or otherwise dispersed.
