Greg Tang was tutoring math in his daughter's class when he noticed something interesting about the dominoes they were using. Each white dot had a pencil mark on it, which meant the children had been counting them one at a time. Mr. Tang taught them to look for patterns instead, and to add and subtract groups of dots in order to calculate the dominoes' value quickly. From there, he developed a new method of teaching arithmetic in a visual and spontaneous way. His method teaches both computational and problem-solving skills, and is so fun and challenging that children forget they are learning math! He believes that all kids are capable of doing well in math, and he has a mission to make math a natural part of every child's life. He has successfully taught his method to children from ages five to ten. Grapes of Math and Math for All Seasons are part of a series of books that will help children gain the range of skills needed for higher math. His books challenge and encourage children to use creativity and common sense to solve problems, rather than formulas and memorization. Greg Tang has an impressive mathematics background. He earned his B.A. and M.A. degrees in economics from Harvard, and he also holds an M.A. degree in Math Education from New York University. He has applied his problem-solving methods in building successful companies and products in a variety of industries. Greg Tang currently lives in Belmont, Massachusetts, with his family.
