I love being a substitute teacher for middle school students. Today’s 8th grade Intro to Physical Science class had a Canvas issue and could not log in to the system to complete the assignment that their teacher left for them. I had to go to plan B — a logic puzzle.

The students, eighth graders, worked in pairs making a visual diagram to solve the puzzle.

After doing diagrams, a couple of students volunteered to explain their process.

I think the class enjoyed The Challenge. Let me know in the comments if you try it.
