EngageNY 60 min(s)

This lesson increases students' level of precision as they read and write time to the nearest minute. Students draw number line models that represent the minutes between multiples of 5, then apply the strategy of counting by fives and some ones to read time to the nearest minute on the clock. In preparation for upcoming lessons, students also add minutes by counting on the number line and clock. For example, they might use the count by fives and some ones strategy to locate 17 minutes and then keep counting to find 4 minutes more.
