CCSS.Math.Content.1.MD.B.3
The standard
Tell and write time in hours and half-hours using analog and digital clocks.
Common Core State Standards for Mathematics · Measurement and Data
What this standard means
Students need to read clocks with minute and hour hands, then match them to digital times. They should know that the short hand points near the hour and the long hand points to 12 for an o’clock time or 6 for a half-hour time.
Mastery looks like saying and writing times such as 4:00 and 4:30 from both clock types, and setting those times on a practice clock. Students often mix up the hands, call 4:30 “6:04,” or forget that the hour hand sits between numbers at half past.
Ways to teach it
- Give pairs mini analog clocks and call out times like 7:00 and 7:30 for them to build and show.
- Ask students to write about two things they do at an o’clock time and two things they do at a half-hour time.
- Show five clock pictures and have students write the matching digital times on whiteboards.
- Use the class schedule to match real events, like lunch or recess, to analog and digital clock times.
