Today in Geometry students finally had enough information to be able to prove that the sum of the interior angles of a triangle add to 180 degrees. One student was so excited and floored by his discovery that he called me over, and told me:
(paraphrase): “Mr. Shah! Mr. Shah! I think what you need to do is keep this proof left undone for the entire year… and hype it up… and then on the very last day of class, have kids discover it!!! It is so awesome!”
In other words, to make this more succinct: BOOM.
PS. No, we didn’t do anything special with the proof. No activity or anything. It just really spoke to this kid.
