The test I gave my math class covered everything we'd studied all year -- fractions, percentages and portions of whole units.
But maybe I could have explained things better. To the question "What portion of a foot is six inches?"
One student answered, "The toes?"
During a Christmas exam, one of the questions was: What causes a depression?
One of the students wrote: "God knows! I don't. Merry Christmas!"
The exam paper came back with the prof's notation: "God gets 100. You get zero. Happy New Year."
A teenage foreign exchange student knew the metric system as well as European colloquialism and slang but he wasn’t well versed with imperial measurement or the use of North American English.
When the exchange student wanted to know what a foot is, the boy that helped him only added to his confusion by saying. “I can give you a hand with that.”
