Units of measurement are standardized meaning that there is a well defined standard way to measure 1 of them.

In this lesson you will learn how to solve a word problem by drawing a bar model. Bar models help us to attain an understanding of how a problem needs to be solved and calculated. Draw a picture graph and a bar graph with single unit scale to represent a data set with up to four categories. Bar notation is an easier way to write a repeating number by putting a line or bar over the repeating numbers.

Here for instance one rectangle or box of the bar model represents a value of 6.
