Measuring with Metric Units

Comparing decimeters and meters

Using decimals to record 80 cm as 0.8 meters
 Ms. Tibbitts' mathematicians have been busy measuring in meters, cm, dm, and mm. They have also been learning how to convert a larger unit to a smaller unit by multiplying, 8 meters = 80 cm.
They converted a smaller unit to a larger unit by writing it as a fraction first, 54 cm is 54/100cm, and then writing the fraction as an equivalent decimal, 54/100cm is 0.54m.
