I'm trying to teach our daughter that sometimes an answer is not wrong but you have to consider the context for the best answer. For instance, on a math word problem, your reply should be a mathematical answer.
She brought home "money math"--a sheet of money related addition and subtraction problems. However, at the end there was a word problem:
"If you put the money from each money bag into one large money bag, will you be putting in an amount that is greater than or less than $10,000?"
My daughter's answer: "Yes, you would."
