Introducing San Diego's most fun and effective math experience! As educators, we find that students' learning development can stall and even regress over the summer. Kids are often sent to a variety of summer camps that focus on athletics and physical activities, but mathematical thinking gets left in last year's classroom. As a result, they fall behind in their next grade and struggle to get back up to speed.

Keep your kids sharp! At Tang Math camp, they will use actual math skills in real world situations while developing a deeper sense of numbers in a really fun way. Every activity - art, singing, engineering, cooking, sports and daily field trips - are all math centered, and campers will learn to actually use math to solve problems in the world around them.
