Build your maze, and then use the coding cards to create a step-by-step path for the Programmable Robot Mouse. Program the sequence of steps, and then watch the mouse race to find the cheese! This deluxe STEM set provides the perfect hands-on introduction to coding concepts for children ages 5+. The colorful components make it easy for kids to design mazes, plan routes, and program their mouse to navigate through obstacles to reach the cheese—learning fundamental coding skills through play without screens or apps. The comprehensive set includes: Programmable robot mouse with lights and sounds 16 maze grids that connect in multiple configurations 22 maze walls and 3 tunnels for creating obstacles 30 double-sided coding cards to plan sequences 10 double-sided activity cards with progressive challenges Cheese wedge goal with reward sound when reached Detailed activity guide with teaching suggestions Children love watching their programming come to life as the mouse follows their commands, building critical thinking and problem-solving skills with every maze they complete. The color-coded buttons make programming intuitive, with forward, backward, left, right, and action functions that can be programmed up to 40 steps in sequence. Parents and teachers appreciate how the set grows with children's abilities—starting with simple paths and advancing to complex mazes that require sophisticated programming solutions. The activity cards provide structured challenges, while the customizable maze components allow for endless creative possibilities. The sturdy plastic construction withstands enthusiastic play, making it ideal for both classroom and home use.
