Extra Credit Idea

Every day, a student brings in a "Stump Mr. Borski Question."  If I know it, game over.  If I don't know it, everyone else in the class can research the question that night and bring in the answer for one extra credit point the next day.  Then the next person brings in a question, related to the unit.

This will not only encourage attendance, but also encourage class participation.  Peer pressure will drive the assigned student to bring in the question for the next day.  If the assigned student does not bring in the question, no one in the class gets the opportunity for the extra credit point.

The Ledge?

Hi Erin,

I dont know very much about it, can you help me answer a couple questions? It will be a giant help if you can help me get started with this.

Thank you soo much,
