On this guided note page, students fill in abbreviations for units of measuring length, put the units in order from shortest to longest, give examples, and record basic conversions (1 ft = 12 in.). U.S. Customary units are labeled on one side, with Metric units labeled on the other side. I have my students complete this page during a lesson about units of measuring length, then keep the page in their binder for reference. It also helps them understand which units belong with which system of measurement.
