Rock Creek Afterschool

Math Games is an enrichment program designed for 3rd, 4th, and 5th graders.

We use card games, dice games, and board games to introduce kids to probability, reinforce core math concepts like fractions and percentages, and build logical reasoning skills.

Games make math fun! The first time we ran this program, we had kids asking us for MORE math worksheets, asking to come to Math Games every day of the week (even weekends), and dubbing our program “SUPER FUN!!!” and “AMAISING” (we’re not teaching spelling haha).

Math Games shows kids the fun, creative side of mathematical thinking and helps them build confidence in their math abilities.

Each session, kids play a new game and then work through math problems that reveal the underlying strategies of the game. In one of our past sessions, for example, we played Guess Who and problem-solved through this worksheet, in which the kids learn that there is an optimal Guess Who strategy (binary search) that guarantees you’ll figure out your opponent’s character in six moves or less.

Math Games introduces kids to advanced topics like binary search, Bayesian updating, and expected value in ways that are accessible and intuitive. Although we’re introducing some advanced topics, our program if a good fit for all 3rd, 4th, and 5th graders who are confident with four function math, regardless of whether or not they consider themselves a math person. The probability concepts we’re teaching have clear, real-world applications, which helps kids build interest and buy into the importance of math.
