Students walk in and are handed a blank half sheet of paper:
After 90 seconds: Teacher again: Put a dot on the midpoint between the houses.
Teacher: Come tape yours up on the whiteboard.
Teacher: Discuss with your table, which midpoint is the best.
The odd thing was, that 99% of the students floated the midpoint.
|Would you call this midpoint a floated midpoint or a foundational midpoint?|
Only a very small handful of students put the midpoint on the ground lined up with foundation of the houses.
(One of the team came in at break, "Ack! no student (out of 30) put the point on the ground! But at least someone suggested it, thank goodness.")
The best midpoint is inline with ground and foundation.
Lots of pro and cons.
Phew. We talked about congruent segments, definition of between, what does middle mean, and finally, definition of midpoint. It was all a worthy discussion, AND, how could have it been better? Oh, and the best house of them all:
The Smurf house!
