I Spy - Positive, Negative, Undefined, Zero

Slope "I Spy" 

I learned this idea from Antwaun Hobbs in an algebra I PLC at Naaman Forest.

Tired of asking, "So is the slope of the line zero... or undefined...?" Try asking this way:

Teacher: I spy a negative slope somewhere in this classroom.
Student 1: Is it the ruler leaning up against the chalk board?
Student 2: No, that's positive?
Student 3: Is it the the rod the flag is hanging off of?
Teacher: Well, that does have a negative slope, but that's not it. Keep guessing...

Thanks to Antwaun for this simple, fun way to turn a question into a game.
