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.

As I told you before, it depends upon the learning objectives for Matthew. It also depends upon what he has been taught and what the curriculum dictates.

D. is definitely wrong. Your teacher is probably looking for C, but this is not a good question or set of answers.

I know.Thanks for your support.

:-) You're welcome.

Your answer, option C, is indeed the correct response for Matthew's teacher to have. Let me explain why.

Using a calculator in this situation can be an effective way for Matthew to check his work and find where he went wrong. It allows him to get the correct answer quickly and easily. However, simply relying on the calculator would not be beneficial in helping him understand the concept or identify his mistake.

Therefore, option A, "Put that calculator away, you can't cheat on your work," is not the appropriate response because the goal is not to cheat but to problem solve. Option 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," is also not ideal because it doesn't encourage Matthew to identify and understand his mistake.

Option D, "Using a calculator is a lazy student's way to solve a problem," is incorrect because using a calculator can be a useful tool when used appropriately, especially for complex calculations or verifying answers. It is important to utilize calculators in a way that promotes learning and understanding, rather than dismissing them as a lazy approach.

Overall, option C is the most appropriate response as it encourages Matthew to use his calculator to find the answer, but also prompts him to review his work, identify his mistake, and understand the correct solution.
