Multiple choice questions...

My dad used to use multiple choice questions very effectively. I've started having fun with them (and hopefully teaching my kids as well.)

Last night's was the following:
"What time do you go to bed?
A. 3 o'clock
B. 8 o'clock
c. 10 o'clock"

"10!"
"I'm sorry that's incorrect. Would you like to try again?"
I repeated the answers.
"8!" she yelled.
"Good job."
Then she said, "thirty," as in eight-thirty.

Tamar and I just looked at each other wondering how she knew that one. Kids pick up the darndest things.
