computational fluency through game play
I’m always on the look-out for games that are engaging for students and that promote computational fluency, so I was super excited to try out Sum of Which: A Game of Numbers and Strategy. The game’s creator, Becky Duprey, sent me a copy of her Sum of Which is Ten Junior game to try in my classroom. My kids gave it a big thumbs up

The goal of the game is to combine numbered tiles to make ten on a crossword-like board. Because our number system is based on the number ten, making ten is an essential skill for young mathematicians. In playing the game, students experience many different ways to compose ten. Just two examples that would work are 3 + 3 + 3 + 1 and 6 + 2 + 1 + 1. Players earn extra points for using more tiles and for placing tiles on specially marked spaces. While the game was created for teachers to use with young children in the classroom, the twist of strategy makes it appealing to “kids” of all ages, and it’s perfect for a family game night.

The demand for Sum of Which is really keeping Becky busy! She recently introduced a new version of the game that features a traditional playing board, with tiles for playing a fraction game (Sum of Which is One) and the original tiles for Sum of Which is Ten. She also has a SMART Board version so you can play whole class and an app is in the works.

Are you ready to try it out for yourself? Of course you are!
