What Worked Well:
It worked really well to have the class working at this pace. Some groups had no problem working through the problems and had a good productive struggle as they increased in difficulty. Other groups had a difficult time making the connection between the colors, functions, and execution. This really allowed me to float through the room and help those groups who needed to talk through their code a little more, and also encourage the groups who had a good understanding to be leaders and help neighboring groups if they needed it.
What I Would Change for Next Time:
Space! I had 8 groups coding at the same time, with most on different task cards. I have huge classes and this became frustrating for students as they couldn't complete the code on the task cards without running into a Dash robot from another group. This inevitably led to groups wanting to "race" each other or go out of their way to try and have their Dash robot run into the Dash robot of another group. Redirection was the name of the game for several groups all hour long!
