This document provides instructions on how to tell time on an analog clock. It explains that clocks have two hands - a long hour hand and a short minute hand. It describes the meaning of the numerals 1-12 on the clock face and how each numeral represents 5 minutes. Examples are given showing how to read times using the position of the hands, such as when the minute hand is in the red or green region to indicate times past or to the hour. The document concludes with a review of the key elements of telling time.
8. How the Clock Works Continued If the big hand is at the 9, 45 minutes has passed (30 minutes + 15 more since it’s another quarter hour).
9. Youtube Example Clip This youtube clip walks you through how to tell time and has many examples. Check it out!
10. Lets Look at Some Examples… Example 1: The big hand is pointing at the 1, meaning 5 minutes has passed. The little hand is on the 12 meaning the hour is 12 o’clock. The time is then 12:05.
11. Examples Cont. Example 2: The big hand is pointing at the 12 meaning it is on the hour, 0 minutes have passed. The little hand is on the 2, meaning the hour 2 o’clock. The time is 2:00.
12. Examples Cont. Example 3: The big hand is just about on the 1 meaning a little under 5 minutes has passed. The small hand is on the 5 meaning the hour is 5 o’clock. The time is roughly 5:04.
13. Examples Cont. Example 4: The big hand is on the 5 meaning that 25 minutes has passed (count by 5’s until you reach numeral 5). The little hand is on 10 meaning the hour is 10 o’clock. The time is 10:25.
14. Final Example Example 5: The big hand is just a little past the 5 meaning a little more than 25 minutes has passed (count by 5’s until you reach numeral 5). The little hand is on the 9 meaning the hour is 9 o’clock. The time is roughly 9:26.
19. Twelve numerals x 5 minutes means that there are 60 minutes in one hour.If the big hand points at the 6, 30 minutes has passed (half of 60). If the big hand points at the 3, 15 minutes has passed (half of 30).

Michigan Department of Education, Web. 14 Oct 2009. <http://www.michigan.gov/documents/MathGLCE_140486_7.pdf>. M.UN.01.03 Tell time on a twelve-hour clock face to the hour and half-hour. M.UN.02.05 Using both A.M. and P.M., tell and write time from the clock face in 5 minute intervals and from digital clocks to the minute; include reading time: 9:15 as nine-fifteen and 9:50 as nine-fifty. Interpret time both as minutes after the hour and minutes before the next hour, e.g., 8:50 as eight-fifty and ten to nine. Show times by drawing hands on clock face.
