Hi, I’m Matthew. I am a sophomore at Valley Christian in Dublin. In my free time, I enjoy playing the piano, playing volleyball, and making logos. I hope that every student can have a great time learning this year— having fun and discovering the excitement of problem-solving through the unique questions they will solve. Looking forward to an exciting year!

Math club

PLAY Math offers a free enrichment course that focuses on critical thinking skills (Verbal, Quantitative, Non-verbal abilities), problem solving and competition math preparation. The class material and curriculum is offered in four classes: one for 2nd graders, one for 3rd graders, one for 4th graders, and one for 5th/6th graders.

This course will be taught by high school volunteers, many of which have multiple years of experience in both teaching and competition. We are a dedicated team of instructors that are passionate in encouraging critical thinking, STEM curriculum, and problem solving to young students. While this course is free and we are a non-profit volunteer organization, we do encourage a small donation of your choice to help cover the cost of the classrooms.
