We took it out of the box in my grade 7 Innovation & Technology class yesterday, and let the kids explore. They discovered quickly how to make a keypad out of a piece of paper and arrows drawn on with pencil, and also made one out of PlayDoh.
It was pretty awesome watching them play Pac Man with the MaKey MaKey - it quickly turned a solitary arcade game into a fun, collaborative one. They were laughing and giggling as they tried to manage the keypad.
The creative potential for this tool is endless - the video above just hints at it. I can't wait to ask the kids innocently loaded questions like, "So, how could you improve the design of that keypad?" and "What other things could you control with this?"
