Is it Morning, Noon, or Night?ampm.jpg

Objective: Students will explore the concept of dividing the 24 hour day into A.M. and P.M. hours

NYS Standards:

2.CN.1 Recognize the connections of patterns in their everyday experiences to mathematical ideas
2.CN.4 Understand how models of situations involving objects, pictures, and symbols relate to mathematical ideas
2.CN.7 Recognize the presence of mathematics in their daily lives
2.CN.9 Recognize and apply mathematics to objects, pictures, and symbols
2.CM.6 Use appropriate mathematical terms, vocabulary, and language

Key concepts:
  1. There are 24 hours in one day
  2. It takes the hour hand 12 hours to move completely around the clock
  3. The hour hand goes all the way around the face of the clock twice in one day


Measure of Success: Students will be able to differentiate between a.m. hours(morning), noon (12:00 in the afternoon), and p.m. (evening/ night time hours)

EDM Lesson: Start the lesson by asking the students the following questions: 1.) How many hours are in 1 day? 24 hours 2.) About how long does it take for the hour hand to move completely around the clock face? 12 hours 3.) How many times does the hour hand go all the way around the clock face in 1 day? Twice
Tell the class that each day starts at 12:00 at night. Ask the students for another name for 12:00 o'clock at night? midnight What do we call the time 12 hours later? 12 o'clock, or noon
Ask whether anyone has heard of A.M. and P.M. Point out that the first 12 hours of a day are A.M. hours and that the second 12 hours of the day are P.M. hours. The hours from midnight to noon are the A.M. hours and the hours from noon to midnight are the P.M. hours. Ask the children to share some things they do during the A.M. hours and some things they do during the P.M. hours.

Differentiated Options:

Audio Learners: Listen to video below

Tactile Learners: Provide "Judy Clocks" for individual students so that they can manipulate hands around the face of the clock. Instruct them to start at 12:00 A.M.and rotate the hands a full 12 hours until it is 12:00 P.M. Repeat process until it is 12:00 A.M. and a full 24 hours has "gone by".

English Language learners: Create a "time telling" word wall. Add the words "midnight" and "noon" to the wall. Include pictures of activities that are typically done at these times below the words. (ex. a child sleeping under the word "midnight" and a child eating lunch under the word "noon".

Visual Learners: Create a large display with three columns: Morning, Noon, and Night. Have students draw or color pictures of daily routines and activities. Have students place these pictures in the correct column. You can create this on a large flip chart, bulletin board, or watch the video demo and use the smartboard activity below.
