“Round the Clock” is a unit on time to the half-hour and digital/analog clocks

Subject:

Math  

Grades:

PreK, K, 1  

Title – Round the Clock
By – Fatima Tuz Zahra
Primary Subject – Math
Secondary Subjects -
Grade Level – PreK-1

Background:

  • Since there are 60 minutes in an hour, children must be able to read and order numbers to 60 before they can read time on the digital clock.
  • Since time is often referred to in fractional terms on analog clocks, it will be helpful if children have an understanding of halves and fourths.

Unit Introduction:

  • Collect different types of clocks and storybooks and/or videos related to time.
  • If possible set up a field trip to an appropriated museum, so that the students can learn more about time.
  • Put useful books in the library corner for the students to read.
  • Locate useful Internet resources.
  • Find or create slide shows listed below.
  • Acquire or make clock reading worksheets.

Day One:

  1. Tracking Game:
    • On the very first day of the unit, get the students to participate in a tracking game (outdoor activity).
    • Draw two paths with the colored chalks from the entrance to the swings.
    • Get the students to choose one.
    • Note down the time with the hourglass.
  2. Start your day with the essential questions.
    • Is time something precious?
    • What does time mean to you?
    • Why do we need time in our daily life?
  3. Explain:
    • You can tell what time is in several ways: the position of the sun in the sky, the length of shadows, the activities people are doing, and clocks and watches.
    • Arrange a puppet show in the class to explain time.
    • Discuss their knowledge and record it in a KWL chart.
    • Show them a movie in their video time ( Back to the Future ).

Day Two:

  1. Relationship of time and clock:
    • Teacher will tell them stories about time.
    • Students will sing poems, Hickory, Dickory, Dock … etc.
    • Students will conduct an assembly presentation on the poem.
  2. Start your day with these questions.
    • How do we measure time? With a ruler? Why not?
    • Direct student’s attention to the clock in the teacher’s presentation.
      • How many big numbers are on the clock?
      • Have students point to the hour hand.
        • Tell them that when the hour hand moves from one number to the next, one hour has passed.
        • What can you do in an hour?
      • Have students point to the minute hand.
        • Tell them that when the minute hand moves from one tick mark to the next, one minute has passed.
        • What can you do in a minute?
  3. Show them a slide show ( What is Time ).

Day Three and Four:

  1. Planning and conducting a survey:
    • Plan for the clock day:
      • Lead a discussion about different timepieces (clock, watch, and timer, hourglass) and the energy sources required to run them (electricity, battery, wind-up movements).
      • Show them images from the computer.
    • Conducting a Survey:
      • Have students survey their homes and count the number of timepieces they find.
      • Ask them to bring their clocks for the clock day celebrations.
      • They should have wrist watches too on that day.
  2. Analyzing data:
    • Guide students to design a chart or poster that reflects their findings.
  3. At the end of the day students will present their clocks in a clock parade.

Day Five:

  1. Human Clock Activity:
    • 12 students hold numbers and stand in a circle.
    • One student holds big and little hands and stands in center of circle.
    • Begin by pointing out the minute hand.
      • Explain how the minute hand moves completely around the clock.
      • Have them time events, such as the length of a TV commercial, class periods with an hour glass, and regular intervals (with a timer).
    • Explain the hour hand.
      • Give questions as you have in previous days and also have them time events around the house.
      • Quiz with flash cards that depict different times on a clock.
        • Start off with flash cards that have a marked clock at every hour.
        • Once mastered, advance to an unmarked clock.
        • Repeat as necessary until they fully understand.
      • It’s a good idea to continue to quiz at least once a week to make sure they don’t forget the fundamentals to learning how to tell time.
    • Explain that some clocks have second hand too, and some times alarm clocks have another hand.
      • Get the students to find such clocks and bring them in the class.
  2. Observing different times of the day:
    • Explain the difference between AM and PM.
      1. Times of prayers (if appropriate in your school)
      2. Mealtime
      3. Playtime
      4. Bedtime
    • Get students to make signs in MS Publisher for different activities.
    • Get the students to conduct a survey:
      • Question: Do you go to bed before or after 8 pm?
      • Choices: Before 8′o clock, at or after 8′o’clock
      • Collecting and representing the data: Each child places a cube in the appropriate pan of the balance.
    • Analyzing the data:
      • At what time do most children in our class go to bed?
      • How do you know?
      • How many of you go to bed at 8′o clock?

Day Six:

  1. Comparing Digital and Analog Clocks:
    • Discuss the differences between the two clocks: digital and a clock with hands.
    • Show them the slide show of digital and analog clocks.
  2. Make a Clock Activity:
    • Divide the class into two groups.
      • One group makes analog clocks with paper plates
      • The other group makes digital clocks with shoe boxes.
        • Make two holes on both sides of the shoe box and pass a stick through them.
        • Attach papers with time written on them with this stick.
        • When you roll the stick, the clock will show different times written on the papers.
  3. Conduct a Survey – Clothes Peg Graph

Day Seven:

  1. Telling time by hour and half hour
    • Discuss the differences between the hour hand and minute hand.
    • Discuss the fraction 1/2.
    • And show the children the interactive clock on the slide show ( Telling Time by Pooh )
  2. Questions:
    • How do we measure time? With a ruler? Why not?
    • What happens if we cannot tell the time? What happened in the story?
    • Would you like to see if you can tell the time? You can tell the o’clock time just by looking at the hour hand.
  3. Practice finding the o’clock.
    • Get the students to work on time worksheets. They will practice drawing hands and showing time.
    • Show them the slide show of digital and analog clocks
    • Ask: Show four-thirty; 4:30 on the digital clock and half past 4 on an analog clock.
    • Continue moving the minute hand around the clock to 12.
    • Ask: What time is it now?
    • Discuss the two ways to read time at the half hour. (4:30 and half past 4)
    • Where is the minute hand at half past the hour?
  4. Analog and Digital Clock Comparison:
    • Identify time on analog clock and create matching time on digital clock using magnetic numbers.
  5. Conduct a survey – Pictograph Activity
  6. Play time games with your teacher
    • Children could have fun snapping fingers to catch a second.
    • They could clench fists as in one potato, two potatoes, etc. to build seconds into a minute.
    • They could then stamp their feet to make an hour.
    • Use www.aramazu.com to access, then build a second and minute game with partner.
  7. Use worksheets to reinforce telling the time.

Plenary:
