This lesson helps students put the minute in perspective.
Start the lesson by asking students to identify words that tell how we measure time. Write the words on the board or a chart. Students might mention such words as day, month, year, hour, second, minute, decade, and century. Focus on the words day, hour, minute, and second. Explain to students that the concept of the 24-hour day dates back to the time of the ancient Egyptians. Make sure students understand that
Write those equivalencies for students to see.
- a day = 24 hours,
- an hour = 60 minutes, and
- a minute = 60 seconds.
When we think of a minute today, we might think of a TV commercial or a common expression, such as Got a minute?, Just a minute!, or In a minute. But when we say Just a minute, do we mean exactly 60 seconds?
We all know that a minute is equal to 60 seconds, but do we really know how long a minute is? The following activities will quickly demonstrate how good a judge of a minute your students are:
- Have students place their heads on their desks. Say "Go"
and then use a clock, watch, or stopwatch to measure exactly
one minute. When students think one minute is up, they should
quietly raise their hands without looking up. At the end
of the activity, identify those students who raised their
hands closest to the 60-second mark.
- Try the activity again. Have students place their heads
on their desks. This time, ask them to quietly sit up when
they think exactly one minute has passed.
- Have students repeat the activity in pairs or groups
of three, timing one another. Have each student take several
turns and record the results. (How many actual seconds had
passed when each student indicated a minute was up?) Which
students seem to have the best concept of a minute?
If you have in your classroom Internet access and a projector that
allows you to project a computer image on a screen, you can
use a fun Web site as the timer for the above activities.
Students will be mesmerized by the Industrious
Clock! Time your "Go!" direction in the above activities
to start when the "seconds" area of the Industrious Clock
Following are more fun activities about time to share with students:
- How many of their spelling words can students write/copy
in exactly one minute?
- Given a sheet of simple addition math facts problems
(for example, 4 + 3 and 6+5), how many problems can students
solve in exactly one minute? (You might try subtraction
or multiplication facts to see how students do with those
compared to addition facts.)
- Have students read aloud a section of familiar text as
fast as they can. (One of the popular Dr. Seuss books might
be a good book for this activity.) Who can read the most
words in exactly 60 seconds?
- Write ten grade-appropriate words on a chart. Give students
one minute to look over the words. Then cover the chart.
Give them one minute to write down as many of the words
as they can remember. Which student(s) remembered the most
- Give students a list of ten grade-appropriate words to
alphabetize. (You might use the same list as used in the
previous activity.) When the time begins, they write a 1
next to the word that comes first in alphabetical order,
a 2 next to the word that comes second, and so on. How many
students accomplished the task in one minute? (For younger
students, you might provide a pack of 26 cards with the
letters of the alphabet written on them. Have students spread
the cards across their desks and, when time begins, arrange
those cards in ABC order.)
One-Minute PE Test
The activities above might open students' eyes to how quickly a minute can pass, however, a minute can seem to pass slowly during a test of physical endurance. For example, have students stand on one foot with both hands raised above their heads for exactly one minute, or have them remain in the up position of a push-up for exactly one minute. Does a minute feel longer during some activities than it does during others?
At the end of the one-minute activities, repeat the heads-down test to see if students now have a better concept of the length of a minute.
- We know that a day is made up of 24 hours and an hour
is made up of 60 minutes. But how many minutes are in a
day? Have students work in pairs to calculate the total
number of minutes in a day. When they are done, see which
pairs got the correct answer. (24 x 60 = 1440 minutes)
Have those teams explain how they got the answer.
- If that was too easy, have students calculate the number
of seconds in a day. (1440 x 60 = 86,400 seconds)
- Have students write their birth dates (month, day, and
year) on a piece of paper. Challenge them to calculate how
many days or minutes old they are. [Since
most students will not know exactly what time of day they
were born, for this activity you can count the current day
and their birthdays as a full day.]
One More Fun Activity: A Verb a Minute
Write a letter of the alphabet on each of 30 index cards. Have students sit in a circle, and then randomly distribute a card to each student. Give students one minute to write on the card a verb that begins with the letter on the card. Then have students pass their cards to the student on their left (clockwise!). Give that student a minute to write a different verb for the letter. When students are stumped, repeat verbs, or write words that are not verbs, they must leave the game.
Have students write a couple of statements describing what they learned from
the activities about the length of a minute. Give them --
you guessed it! -- one minute to think of a reply and one
minute to write it down. Some students might point out that
a minute seems to go quickly some times (when racing to complete
a math facts test, for example) and more slowly at other times
(when standing on one foot, for example). Others might note
that they learned that a lot can be accomplished in a minute;
that a minute can be a valuable unit of time; or that they
were amazed to learn how many minutes they already have lived.
Alternative assessment: Have students write a haiku
to explain what a minute is. (This activity breaks slightly
from the haiku pattern. Haiku are usually about nature. A
"minute" is not a natural phenomena; the nations of the world
have agreed on what a minute is.)
