Teacher: "If homework was worth 3 points, how many of you would do it?"

Teacher: "Okay, if homework was worth 2 points, how many of you would do it?"

Teacher: "If homework was worth 1 point per day, how many of you would do it?"

Teacher: "If homework was not graded, how many of you would do it?"

Teacher: "Johnny, why would you still do your homework?"

Teacher: "Thanks for your honesty, Johnny. Suzy, why would you still do your homework if it was worth zero points?"

Teacher: "I do, too, Suzy. Thanks for your enthusiasm. Frank, why wouldn't you do your homework if it wasn't graded?"

Teacher: "Frank, if you didn't do your homework for this unit, how well do you think you'd do on the test?"

Teacher: "Thanks for your honesty, Frank. If you didn't do your homework again for the next unit, how well do you think you'd do on the test?"

Teacher: "Frank, how many tests do you think you'd have to fail before you realized that doing your homework is a good idea?"

Teacher: "Okay, now that you know that...why wouldn't you just do your homework?"
