Class Openers

Class Opener – Day 25 – Stupid Student Tricks

David Letterman has his Stupid Pet (and human) Tricks…so today in class we started Stupid Student Tricks (please read that carefully —- stupid is describing the trick).  My classes understand I will begin each day a short opener, and I have now given them the opportunity to participate in the process.  On Edmodo, they can submit an idea for a class opener – it can be a video, a challenge, a picture, a story – to share with the class. Every Wednesday, one idea will be chosen to be the class opener. Chosen ideas will receive a bonus quiz grade during the semester. I’m looking forward to the ideas the kids choose to share!



My first student “opener” volunteer is Ryan, who shared his skill of identifying perfect cubes.  Calling volunteers to the board, he asked them to think of a number from 1 to 100, and share it with the class (but not him).  Then, the volunteer cubed the number and the product was written on the board.  Within seconds, Ryan gave the original number.  It’s a pretty good trick, and one he has become quite quick with.  To show how the “trick” is done, Ryan shared a video from Scam School, a neat series of everyday tricks and scams.  Enjoy it here:
