1. Elapsed Time. To help children gain a sense for the passing time,
elapsed time can be experienced through hands-on activities. For
example: How long is math class? How long do you sleep? Ask
students to set the clock to the beginning time of math class, then turn
the minute hand until the proper end time is reached. Then have
students crank out ten hours (a typical sleep period for children) on
the clock. Which is longer? How much more?
2. Adding Elapsed Time. Explore elapsed time using the Big Time™
Learning Clock™. First, have students set the clock to a time value that
you have written on the board. Give students an elapsed period of
time, such as three hours, and have them add the time onto the clocks.
Start simple, and build to more challenging problems.
3. Subtracting Elapsed Time. Work “backward”with elapsed time.
Have students set the clock to the time value you have shown on the
board. Tell students that this is an end time, and a certain amount of time
has elapsed. For example, show children the time 4:00. Tell them 2 hours
have elapsed before this time. What was the starting time? Students turn
the clock hands backward to come up with the answers.

4. Setting a Schedule. Have students replicate the daily class schedule
on paper, then follow along with the clock. How long does each subject
last? How long is the school day? Ask students to write out a typical

schedule for their entire day. For each activity, have1them calculate the
¨
elapsed time using starting and ending clock times. Have students
compare the times spent on shared activities.

5. The Second Hand. Explore the second hand using a classroom clock.
Ask students, “Each time the second hand goes around once, how far
does the minute hand move? How many seconds are there in a minute?”

6. AM and PM. The hour hand of a clock rotates twice each day. To
keep the morning hours separate from the evening hours, people use
the terms AM and PM; AM is used to describe the morning hours and
9
PM is used to describe the afternoon hours. Ask students how many
hours there are in a day.
