Round each measurement to the nearest 10 cm. When you complete the first three, choose two things that you would like to measure in centimeters. Write what you measured, how long it is in centimeters, and fill in the rest of the chart to estimate the amount to the nearest 10 centimeters. On the 2nd page, look at the liquid in the beaker. Estimate whether the liquid is closer to 20mL or 30mL.
