• 160 + 240= 400

Jesse practices the trumpet for a total of 165 minutes the 1st week of school and 245 minutes the 2nd week. Estimate the total amount of time Jesse practices by rounding to the nearest 100 minutes.

• 170 + 245= 420

• 100 + 200= 300

• 200 + 200= 400

• 200 + 100= 300

How does estimating help you check if your answer is reasonable?

• It doesn't.

• You can only tell if you round the nearest 100.

• It's not precise enough.

• You check your actual answer to the estimated answer to see if the the numbers are close.
