As I prepare for coaching Middle Schoolers here in Waupaca for FIRST Lego League, I am trying to teach kids to code the SPIKE Prime Lego robots. This has its challenges. Some kids take to coding well, and some need more visuals to guide them. Teams may also want to whiteboard out their coding concepts.
