In this lesson, students extend their understanding of metric length conversions. In the previous lesson, students converted from a larger unit to a smaller unit, often resulting in very large numbers because they multiplied by powers of 10. In this lesson, students convert from a smaller unit to a larger unit, resulting in a smaller number, and sometimes, a decimal. Students notice how the digits in a number shift to the right when dividing by powers of 10 and, consequently, whole numbers often become decimals (MP7).

If you were to teach this lesson again, what would you do differently? How would your proposed changes support students’ learning?
