Recognize halves within a circular clock face and tell time to the half hour.

In this lesson, students practice telling time to the half-hour on both analog and digital clocks, a skill introduced in the previous lesson. They write times shown on a clock face, show given times on their own personal clocks, and solve simple word problems involving time. (For example, "Kim's dance class starts at 3 o'clock. The class lasts half an hour. What does the clock look like when the class ends?")
