After a quick review of if/then/else logic statements, we tried to visually represent Boolean operators using Venn diagrams. Using the whiteboard, we drew the relationship between snowboarders and skiiers in the class.  We learned that:

  • 14 students ski
  • 4 students snowboard
  • 1 student doesn’t ski or snowboard

Using Boolean operators, we examined our data and found that:

  • 11 students ski NOT snowboard
  • 2 students snowboard NOT ski
  • 2 students ski AND snowboard
  • 1 student NOT ski
  • 1 student NOT snowboard
  • 1 student NOT ski NOT snowboard

Once our group application of the Boolean operators was complete, students began individual assignments adding AND/OR/NOT into Scratch and combining them with the logic statements they had already created.
