Students will look at analog and digital clocks and correctly say and write the time in the format “___ :30” or “_____ o’clock,” using the : (colon) symbol as necessary. Students will understand that two onehalf hours equal one whole hour. Students will understand that the minute hand signifies “30” when it points to the six. Students will likely be confused by the fact that the number six on the analog clock represents both “six o’clock” and “thirty minutes” depending on whether the hour hand or the minute hand is pointing to it. Students may not understand which hand is which, confusing the minute and hour hands.
Key Concepts:
 We can tell and write time to the half hour using analog and digital clocks.
Prior Knowledge Needed:
 Calendar and days of the week
 The idea of a schedule, such as “art class is from 9:00am  10:00am”
 Numbers 1  30
 Telling time to the hour on analog and digital clocks (Grade 1, Unit 5; 1.MD.B.3)
Units on the Horizon:

 Relating Skip Counting to Time; (Grade 2, Unit 4)
Lessons

Lesson objective: Understand that two half hours are the same as one hour. Students bring prior knowledge of telling time from determining the hour on analog and digital clocks. This prior knowledge is extended to half hours as students determine what i...

Lesson objective: Read analog clocks to the half hour. This lesson helps to build fluency with recognizing the minute hand on the six. Analog clocks set to the hour and half hour are used here because they highlight the role of the minute hand in tellin...

Lesson objective: Understand why the :30 displayed on a digital clock represents the same thing as when the minute hand points to the six on an analog clock. Students bring prior knowledge of reading analog and digital clocks from telling time to the ho...

Lesson objective: Interpret time to the half hour as represented on analog and digital clocks. This lesson helps to build the procedural skills of telling time on clocks by having students look at multiple clock formats. Analog and digital clocks are us...

Lesson objective: Solve problems by creating an order of events based on information from analog clocks. This lesson provides an opportunity for students to apply their knowledge and understanding of telling time to the hour and half hour to a reallife...
