Block-based coding

Block-based coding turns each instruction into a colored tile on a screen. A child drags tiles like move forward, turn left or repeat three times into a stack, and the robot runs the stack from top to bottom.

The blocks only fit together in ways that make sense, so a child cannot make a typing mistake. That lets them focus on the order of steps, which is the core idea of programming.

Many kids’ robots start with blocks and later let the child switch to typed languages such as JavaScript or Python, often showing the same program in both forms.
