This lesson introduces the idea of a length unit. Students lay centimeter cubes alongside the length of objects as students learn that the total number of cubes laid end to end with no gaps or overlaps is the length measure of that object. The objects being measured include many of the same objects from previous lessons so that students can add greater precision to their measurements. For example, the length of a crayon can now be described not only as shorter than a paper strip, but more precisely as 9 centimeter cubes.
