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.

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.

This fascinating study of mathematical thinking among sub-Saharan African peoples covers counting in words and in gestures; measuring time, distance, weight, and other quantities; manipulating money and keeping accounts; number systems; patterns in music, poetry, art, and architecture; and number magic and taboos. African games such as mankala and elaborate versions of tic-tac-toe show how complex this thinking can be. An invaluable resource for students, teachers, and others interested in African cultures and multiculturalism, this third edition is updated with an introduction covering two decades of new research in the ethnomathematics of Africa.

Hands-On Math: Building and Understanding a Parabolic Reflector introduces the reader to conic sections and explains how to build an inexpensive parabolic reflector. Building a parabolic reflector and working through the associated math is a project easily tailored to classrooms from Algebra I through Calculus. Hands-on and enjoyable, this project is ideal for demonstrating the beauty and power of math in every day living. The text includes detailed building plans and step-by-step instructions (accompanied by numerous photographs) for designing and building a parabolic reflector. The mathematics of the parabola are presented including a derivation of the equation of the parabola from its geometric definition and multiple proofs of the reflective property of the parabola. Methods for working with quadratic equations - factoring, completing the square, and graphing - are presented. Multiple problem sets are provided for practice, along with a complete answer key.
