This tape contains excerpts from a two-day workshop held in mid-August 1991 for teachers who had successfully used Project MATHEMATICS! materials in their classrooms, specifically The Theorem of Pythagoras, The Story of Pi , Similarity , and Polynomials . Broader issues in mathematics education were also discussed: for example, the role of visualization, the use of manipulatives, and different learning and teaching styles. The teacher participants explain how Project materials have been used in a variety of classroom settings, from grades 8 to 13, and how they have adapted to new ideas and new technology in creative ways that enhance their teaching and motivate their students to become excited about learning mathematics.
