In this lesson, students practice using "rulers," even though they are not using standard units of measure. The students go around the room in search of various items, and they use a "nonstandard ruler" to measure the items once they are located. This less bridges the use of non standard units to using a ruler.
This lesson supports the alignment of Mathematical Practice Standard MAFS.K12.MP.5.1: Use appropriate tools strategically, as students use various tools to measure lengths.
