Unit 6, Lesson 13
Is It a.m. or p.m.?
Grade 2
Preparation
Lesson Narrative
In previous lessons, students learned to tell time to the nearest 5 minutes, using analog clocks.
In this lesson, students practice telling time to the nearest 5 minutes. Students recognize that the hour hand goes around the clock twice each day, so a.m. and p.m. are used to distinguish between morning and night. Students relate a.m. and p.m. to specific times and activities during the day.
- Representation
None
- Comprehend that the notation “a.m.” refers to times of day in the morning and “p.m.” refers to times of day in the afternoon and night.
- Explain (orally) how to determine if a time should be labeled as “a.m.” or “p.m.”
- Let’s read and write times, using a.m. or p.m.
Required Preparation
- Create the Hours in a Day Timeline to display to students in the Launch.
- Label the representation as “1 day.”
Teacher Reflection Questions
How helpful is the linear representation of 1 day for developing an understanding of the repeating 12-hour cycle? What more do students need to build an understanding of the hours that make up a.m. versus the hours that make up p.m.?
