“I created Break Apart to teach kids the best strategies for adding, subtracting, multiplying and dividing. When kids learn the proper techniques, arithmetic is easy and more advanced concepts follow naturally. Our strategies are intended to develop the algebraic thinking skills required for higher math.”

“With Numskill, my goal was to give kids a fun way to master their addition facts. But instead of giving kids a problem and asking them to figure out the answer, I realized it’s more beneficial if they have to figure out both the problem and the answer. This increases the number of problems they have to solve, and adding color increases it even more. Lots of practice is the key to mastery.”

“Numskill gave me the idea for Kakooma. One day it occurred to me that a series of Numskill-type problems could be used to create one final problem. This “puzzle-in-a-puzzle” idea became the unique twist that makes Kakooma so compelling. Solve a series of mini-puzzles and their answers turn into another puzzle! We started with addition of positive whole numbers and now have negative numbers, and multiplication.”

“I created Math Limbo to help my own kids become better at math. The reason it’s such an important game is that it gives kids practice breaking numbers apart. There are many games that teach addition, but very few focus on decomposing numbers. Even fewer make a connection to subtraction as well. I believe that, together with my other games, Math Limbo gives kids the practice they need to develop great computational skills.”
