Lesson objective: Practice converting units of time from larger units to smaller units.

This lesson helps to build procedural skill with conversions of time. A function table is used here because it highlights the connection between converting from larger units to smaller units and multiplication. This work develops students' understanding that you can compare units of measure using multiplication.

Students engage in Mathematical Practice 7 (look for and make use of structure) as they look at the relationship between hours, minutes, and seconds to convert larger units of measure to smaller units of measure.
