What This Standard Means

What Students Need to Do

Students name minutes and hours as units for measuring time. They connect the minute hand to minutes and the hour hand to hours.

What Mastery Looks Like

Students identify minutes and hours as units used to measure time. They explain that 60 minutes make one hour and connect each clock hand to its unit.

Common Misconceptions

Students may think the long hand shows hours because it is larger. They may also read each clock number as one minute instead of five minutes.

How to Assess It

Show a clock with labeled hands. Ask, “Which hand helps track minutes, which tracks hours, and which unit is longer?”

Lesson moves

Ways to Teach It

  1. Give pairs teaching clocks and have students move the minute hand through 60 minutes while watching the hour hand advance.

  2. Ask students to write one activity that takes about a minute and one that takes about an hour.

  3. Play Minute or Hour by naming activities, then have students hold up the matching unit card.

  4. Compare the time needed for brushing teeth, eating lunch, and watching a movie, using minutes or hours.
