Explore the use of scale on a number line. Select a ruler displaying a helpful scale such as tens. Look at a pair of numbers such as 90 and 120 marked on a number line. Identify the number corresponding to another point. Or locate another point on the number line to complete a series of three numbers. Apply a marked scale to help estimate the relative distances. This learning object is one in a series of seven objects. Some objects in the series are also packaged as a combined learning object.
