What a learner can do afterwards

You already know how to compare two things and say which one takes longer. Now you will line up three or more events by how long they last, from the shortest to the longest.
Mia had a busy morning. She brushed her teeth for 2 minutes, walked the dog for 15 minutes, and watched a show for 30 minutes. Shortest to longest: teeth, then the walk, then the show.
To sequence intervals, pick the shortest one first. Then look at what is left and pick the next shortest. Keep going until every event has its place in line.
Sequencing time means lining up events from the one that took the least time to the one that took the most.

Telling time review
Reading a clock is like reading a story. First find the hour, then find the minutes. Put them together.
Draw hands to show a time. Check that the short hand sits just past the hour when minutes are large.
Converting units of time review (seconds, minutes, & hours)
Time comes in seconds, minutes and hours. Sixty seconds make one minute. Sixty minutes make one hour.
Count around the clock to feel it. The long hand moves fast for minutes. The short hand moves slow for hours.
Telling Time to the Hour
Clocks show hours and minutes. The short hand points near the hour. The long hand points to the minutes.
When the long hand points straight up, it is o clock. When it points down, it is half past. Practice with a toy clock.
2nd Grade Telling Time
Second graders learn to tell time to five minutes. Skip count by fives around the clock. Each number means five more minutes.
Say the time out loud. Quarter past means 15 minutes after. Half past means 30 minutes after.
