This Problem Set is a part of the Lesson 13, Unit 8, Grade 2. In this lesson, students start to relate each of the 12 numbers on the clock face to intervals of 5 minutes. They use skip-counting to count up to and down from 60 by fives in preparation for telling time to the nearest 5 minutes. Next, they learn to tell time by counting numbers on the clock face for the minute hand, as well as relating the position of the hour hand to the correct hour.
