Thinking Outside The Box
I am a private tutor. I’ve given one of my students, a fifth-grader, an exercise which I call “reverse word problems”. The student gets a list of equations, and for each equation, they have to come up with a word problem that could fit the given equation. I am reading the answers he’s written.
Me: “You’re a scientist with four-fifth of a dead cow. You’re in a duplication room and you duplicate two-fifths of it. How much of a cow do you have?”
The equation for this one was “4/5 x 2/5.”
Me: *Laughing* “A… a scientist with a dead cow? Really, kid?”
Student: *Giggles* “Well, obviously. It has to be a dead cow. If you have four-fifths of a cow, how can it possibly still be alive?”
Me: *Pause* “You got me there.”
I keep reading.
Me: “You have one dollar and six friends, and you decide to split the dollar evenly between your six friends. How much of a dollar does each friend get?” *Pause* “Wait a minute; this doesn’t work.”
Student: “Yes, it does.”
Me: “No, think about it. Can a dollar divide into six equal parts?”
Student: *Indignantly* “Yes, it can!”
Me: “Okay, how?”
Student: “You take a pair of scissors and cut the bill into six equal parts!”
Me: “I— Well. That’s…”
The student laughs.
Me: “…genius. Forget I said anything.”
This kid is going places.
