# Lesson 15

Write Times

### Lesson Purpose

The purpose of this lesson is for students to understand that times called half past are represented as ___:30. Students write time in hours and half hours to match analog clocks.

### Lesson Narrative

In the previous lesson, students connected “half past” the hour to half of an analog clock face. They told time in hours and half hours on clocks that only had an hour hand. At the end of the lesson, they learned that when it is half past the hour, the minute hand points to the 6.

In this lesson, students connect half of an hour to the digital form ___:30. Students write time in hours and half hours based on analog clocks. They add the digital form to the half past clock cards.
