Now, Greg is putting everything he has learned and created on one website. It is an important part of his mission to help children and adults of all ages become better in math. Greg is working hard to create better teaching methods, shift the focus to more critical, abstract thinking skills, and make important mathematical concepts easier and more intuitive.

Greg believes that to be good in math, children need to learn to think abstractly at an early age. When kids learn to think abstractly and efficiently about numbers in groups rather than counting or memorizing, they can be taught common sense strategies that make calculations fast and easy. Greg believes that being able to connect and generalize these strategies across problems and operations is the key to thinking algebraically.

It is a common misconception that people who are good in math are good at memorizing. Quite the contrary, they’re abstract thinkers who are good at understanding and generalizing concepts, then applying them to different problems and situations. Greg’s website asks kids to solve problems quickly in their heads, and to use specific strategies in order to develop specific skills.

Greg writes children’s picture books as an author for Scholastic. He is also an author for Houghton Mifflin Harcourt’s elementary math textbook program. His work has been included in many other major textbook programs in the United States as well, including Math Expressions, Go Math, Everyday Math and Investigations.
