Polyup is a free and open playground where students can experiment with numbers and functions. It converts the abstract concepts of mathematics and computer science into tangible and interactive objects in one easy-to-learn, visual environment. Using this environment, Polyup connects to real-world objects so that players can mod (modify) the world around them, with math. For example, students can mod robots and drones in Polyup, or they can mathematically modify their classrooms in augmented reality!
