# Lesson 14

Half of the Clock

### Lesson Purpose

The purpose of this lesson is for students to learn about the position of the hands on an analog clock at half past the hour.

### Lesson Narrative

In a previous lesson, students learned how to tell and write time in hours. In a previous section, students partitioned shapes into two equal pieces and identified each piece as “a half of” the shape.

The purpose of this lesson is for students to learn about the position of the hands on an analog clock at half past the hour. They analyze how the hands on the clock move as time goes from one hour to the next. They see that half past the hour is when the hour hand is half way between two numbers and the minute hand is halfway around the clock. They create new clock cards that show half past and add the minute hand to the clocks.
