Prior to Design Lab, I had put the 9V battery into all 5 of our MeeperBots. The screw was a little tricky so hopefully our rechargeable 9V batteries will have a long enough life that I don't need to do this frequently.
I put out the MeeperBots next to the legos and watched as our students started to check them out. Each student downloaded the MeeperBot app onto their iPad. Honestly I did nothing except show them how they could tell if they were connected. I need to rename the MeeperBots because students wanted to connect to specific colors.
