Somebody’s Slope Is About To Become Much More Negative

, , , , , , | Learning | June 3, 2021

In my junior year of high school, I am put in a math class with a teacher fairly fresh out of school. She is by no means a bad teacher, but because she is new, she is a bit naive. For example, other math teachers usually create two similar but different versions of a test with different colors that alternate each row so that people can’t cheat, but she didn’t do this… at least at first.

It must have become obvious to her that people were sharing answers. On our fifth quiz, I am working on it and realize the girl next to me is copying my answers. Whatever, I don’t really care. But then, the graph on her quiz catches my eye and I realize that her slope is negative while mine is positive, and then it hits me: they’re different quizzes. I just let that ship sail and let her do what she wants.

Quiz scores come back and my classmate gets a zero while I get a perfect score. At parent-teacher conferences, we get to reminisce about that interaction, and I get to tell my teacher that I realized both that my classmate was cheating and that they were different tests and chose not to try to alert her, which tickled my teacher pink.

She started color-coding the versions after that, but she put a lot of cheaters to shame on the first one!
