What is a reason you might want to ESTIMATE to find the answer?

• To make sure you have enough money to pay for your snacks!

• To make sure your answer to a super complex math problem is reasonable.

• You went shopping and FORGOT to bring your calculator (oh, yes, you also forgot your super smart phone).

• You are driving to the beach for a vacation. You are stuck in the back seat. You know ABOUT how fast you are going and ABOUT how far you are going. You would like to know ABOUT how much LONGER til you GET THERE!

• Because it is a question in my math homework :(
