It is a visualized mathematical function application (VMFA) for young students. Parametric design is adopted in the VMFA to make math symbols simply. It is represented in interesting parametrical shapes that can be printed by 3D printer. After adjusting mathematical parameters, mathematical functions can be easier understood by students. Meanwhile, it enriches the meaning of interaction. Gamification is to increase students’ interests of learning mathematical functions. It's really a funny solution for the young generation to get knowledge.
