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 offered in two classes: one for 2nd/3rd graders and another for 4th/5th graders. Please Sign Up: HERE

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.

Here are some past contributions to the community from PLAY Math:
• $875 donated to PLAY Leadership (2022)

• 1,300 masks/$920 to local firefighters (2020)

• $659 to Tri-Valley Chinese American Community for PPE masks (2020)
• $287 in supplies to San Jose Angels Foundation Homeless Drive: boxes of chips, personal hygiene products, etc.
• Around 1000 books distributed to ReWA for refugee children in Seattle
• $100 donated as school supplies for the San Jose unhoused products, etc.
