Big Ideas: Measurements of time given in large units can be written as an equivalent amount smaller units by using multiplication. Hours can be written as minutes, and minutes can also be written as seconds. In this lesson students will be applying their knowledge of unit conversions involving units time. This is an open-ended task in which students will have to find a possible time that would result in a personal record for a triathlete. Vocabulary: hour, minute, second, equivalent, convert Special Materials: number line
