Order three objects by length; compare the lengths of two objects indirectly by using a third object.
Why water teaches this standard well
Students order three garden hoses, or three sticks used to mark puddle depth, from shortest to longest, then use one hose as a go-between to compare two others that were never placed side by side. Indirect comparison through a third object is the reasoning behind using a standard ruler later.
