The Power of Mathematical Visualization teaches you these vital problem-solving skills in a math course unlike any you've ever taken. Taught by award-winning Professor James S. Tanton of the Mathematical Association of America (MAA), these 24 half-hour lectures cover topics in arithmetic, algebra, geometry, number theory, probability, statistics, topology, and other fields-all united by fascinating connections that you literally see in graphics and projects designed by Professor Tanton. In demand worldwide for his teacher and student workshops, Dr. Tanton is MAA's Mathematician-at-Large-a globe-trotting advocate for teaching math "with beauty and joy and wonder and humanness," as he was recently quoted in The New Yorker magazine.
As an example of Dr. Tanton's approach, see the many applications of a simple game called dots-and-boxes, which is the gateway to a universe of mathematical concepts and operations- some of which might seem quite unrelated:
Long division: Elementary school students typically learn a traditional method of long division that works but can seem abstract. By contrast, the dots-and-boxes approach is more intuitive and actually explains why the traditional method works.
Binary arithmetic: The binary base system uses only 1's and 0's, which is how computers calculate with on/off switches. The game of dots-and-boxes makes arithmetic in binary and any other base system child's play-even for fractional bases.
Polynomials: The study of polynomials in algebra is, astoundingly, mostly a repeat of grade-school arithmetic, done in base x rather than base 10. Dots-and-boxes comes to the rescue for intimidating-looking polynomial problems, and even for dividing polynomials.
Decimals: With dots-and-boxes, you can demonstrate that every fraction has an infinitely long decimal expansion with a repeating pattern. For example, 1/3 = 0.33333...; 1/4 = 0.25000... (the repeating pattern is zero); and 13/99 = 0.131313....
And that's just the beginning. Once your mind is attuned to think about mathematical relationships in terms of visual models such as dots-and-boxes, the insights start to pile up. That's when you are truly doing mathematics-not just mechanically following an algorithm or formula you memorized in school. Visual thinking lets you see the logical steps that lead to an answer and grasp the solution that must be true.
Throughout the course, Dr. Tanton often adjourns to his tabletop lab to illustrate mathematical ideas with activities that you can try at home, involving poker chips, marbles, strips of paper, and other props. Some seem positively magical, like the miraculous division of a pile of jelly beans in the last lecture, where your method is inspired by a simple folding pattern.
