## Ideas from Active Algebra

“Trashketball”
The presenter gave us this idea of actually encouraging kids to throw paper in class. In her version, students draw a number from 1 to 7 — that is the number of tosses the student makes into a trash can. For each toss, the student (and the class) calculates the fraction of tosses that the student has made (ex. $\frac{1}{1}, \frac{1}{2}, \frac{2}{3}$).

The variation S and I thought of was to group students at each table for a kind of “semi-final” competition. They could roll a die to determine how many tosses they get. The winner of each table then advances to the “final” with the big trash can.
