So for those of you who don't know, I teach math at a high school. One day this week I gave my classes an assignment that was due at the end of the period. With the potential of one person in the group doing all the work while the other just write down the answers, I told the class, "You have to show your work."
Student: "What? That's not fair!!"
Teacher: "Really? You think it's fair to just copy down the answers?"
We were finding Mean, Median and Mode. I told the class they had to at least show the work to find the mean.
