Matthew sits at his desk unable to figure out the answer to a division problem. He reaches into his desk

and pulls out a calculator. What is the correct response for Matthew's teacher to have?
A. "Put that calculator away, you can't cheat on your work."
B. "That's fine to use your calculator, don't worry about that problem. Maybe you'll be able to do the next one on your own."
C. "Use your calculator to get the answer, but then go back to see if you can find where you went wrong."
D. "Using a calculator is a lazy student's way to solve a problem."

my answer is c.

I don't think there is a "correct" response. A lot depends upon the educational objectives for this student.

Yes, your answer is correct. The correct response for Matthew's teacher would be C. "Use your calculator to get the answer, but then go back to see if you can find where you went wrong."

By allowing Matthew to use his calculator, the teacher encourages the use of technology as a tool to aid in problem-solving. However, the teacher also emphasizes the importance of checking one's work by suggesting that Matthew should go back to see if he can identify where he made a mistake. This approach promotes self-reflection, critical thinking, and learning from one's errors rather than relying solely on technology.
