By arranging wooden pieces through slots, the "small car/wooden figure" can be driven to run on a 25 × 25 cm chessboard, completing tasks such as mazes and number jumps. Interdisciplinary integration: Mathematics: coordinates, angles, simple algorithms. Physics: Friction force comparison (changing different wheel materials). Art: Comes with blank wooden pieces and whiteboard pens, children can customize command icons. Wood color+four-color silk screen printing instruction symbols, drawer style color box, convenient for classroom storage. Classroom usage example: Move the car from A1 to C3 and avoid obstacle blocks. Use the 'loop' command to make the car run 2 circles along a square trajectory.
