I was unimpressed on Halloween night by the number of college students I found trick-or-treating at my door. (Seriously, college students? It's questionable by the time the kids are 13 or 14.) I'm thinking I might construct a more age-appropriate treat for college students next year, like a really interesting pamphlet on a cool math problem, and tell them it's their intellectual treat for the night. If they want candy, they (unlike the six year-olds) can drive down to the grocery store and buy some.
But today my math class for elementary education students was working on an activity involving adding and subtracting integers. It uses a cute little paper copy of a clown who walks forward and backward on a number line "tightrope". It's a nice activity. When I was cleaning up after class I found a left-behind clown that some student had taken upon themselves to add genitalia to and portray performing an obscene act. (These students want to teach grade school?)
I am not overwhelmed with the cuteness of my students at the moment.
