A mathematics teacher came into the faculty room after she'd been watching a basketball game. Her face was glowing. "I've got the greatest idea for teaching!" she exclaimed.

"What do you mean? What's the idea?" asked a couple of colleagues.

"Well, you know how hard it is for us to really teach fractions? The kids just don't seem to be motivated to learn them."

"Yes, it's true," said a fellow math teacher. "So?"

"Well, the solution is to change the system of scoring in basketball. A free-throw, 2 2/3 point; a basket, 3 1/7, and a foul, 7/8 points!"
