His website,, offers many free on-line games for students to play that reinforce core math concepts.

During his visit, he focused on number bonds. What are number bonds? Ask any first or second graders --- they have the answer.

A number bond is a useful tool in understanding numbers and basic arithmetic. They are the relationship between a number and the parts that make it. "A whole thing is made up of parts. If you know the parts, you can put them together (add) to find the whole. If you know the whole and one of the parts, you take away the part you know (subtract) to find the other part."
