LESSON PLANNING OF TIME

Subject Mathematics

Grade 5^th

Students` Learning Outcomes

• Convert hours minutes, minutes to seconds and vice versa.

Information for Teachers

• 1 hr = 60 minutes
• 1 minute = 60 seconds
  

GSM = Greater to Smaller Multiplication

SGD = Smaller to Greater Division

Key terms: minute hand, hour hand

• During this lesson teacher will consult the textbook at all steps where and when necessary.

Material / Resources

Writing board, chalk / marker, duster, wall clock or few wrist watches, so that students can observe that 60 ticks to make one minute, textbook

Introduction

• Brain storms the students on the following question;
• How many times during the day, you use the word ‘time’?
• Expected answer would be as;

o   What time is it?

o   It`s time to pack up.

o   You`re wasting your time.

o   It`s time for watching TV.

o   Be sure to handover your work on time.

o   It`s lunchtime.

• Discuss with students some famous quotes about time, e.g.

o   Time heals all wounds. (Geoffrey Chaucer)

o   Better late than never.(Lu Hsun)

o   Time and tide waits for no one.(William Bradford)

o   Time flies.(Proverb)

• Ask: Why is time so much important? What do you say about it?
• Ask: Do you remember any incident or story that emphasizes the importance of time?
• [Let the students think and share with the whole class]
• Tell them that we will study about the conversion of hours, minutes and seconds.

Development

Activity 1

• Review the valuation among the different units of the time.
• Ask the students;

o   Which hand tells the quarter of an hour? [minute hand]

o   How long does it take the minute hand to complete one round? [you may allow them to observe their watches, class clock or the clocks they bring] [there are 60 ticks or seconds to make one minute]

• Write on the board 1 minute = 60 seconds.
• Ask them: “Have they ever noticed? How many ticks or seconds the min hand takes to come back to 12 after completing a round?” complete circle from? [60 seconds]
• Ask them:

o   When the long hand moves from 3 to 4. How many minutes is that? [05 minutes]

o   When the long hand moves from 1 to 4. How many minutes is that? [15 minutes]

o   05 and 15 are the multiples of which digit?

• Discuss with students to find out the result that the movement of the hands of clock work according to the timetable of 5.
• Ask:

o   How many total minutes are shown on the clock? [12 x 5 = 60 minutes]

• Tell them if you count the dots on the clock, they are also 60.
• Ask: “When does the hour hand move?” [When minute hand completes one circle after every hour]
• Tell: Hence we can say that 1 hour = 60 minutes.
• Tell: When 60 steps by minutes hand are completed then hour hand takes one steps.
• The conclusion of the discussion is;

o   1 hour = 60 minutes

o   1 minute = 60 seconds

Activity 2

Individual Activity:

• Ask the students: “After going back home, what is your daily routine and how much time do you spend on each activity?”
• Fill in the given table:  
  
• Once they complete the first four columns of the table ask, “Can you express this duration in seconds?” 
• How would you do that? [Observe how many of them can identify multiplication?]
• Write one example on the board as 1 minute = 60 seconds then 30 minutes = 60 x 30 seconds = 1800 seconds.
• Allocate time for the completion of column no. 5. Review answers for corrections.
• Do you remember GSM?
• Remember the term was introduced in the length unit ‘GSM- Greater to Smaller Multiply’ 
  
• What are we doing? [Multiply]
• “Yes: we are doing GSM”. For changing a Greater unit to a smaller unit we are multiplying.
• Say: “Tell me hours. I will tell you minutes?” for example; how many minutes are there in 13 hours? Let them think and respond them tell them the correct answer. [13 x 60 = 80 minutes]
• Conclude that there are 60 minutes in 1 hour and we ‘multiply’ to convert hours in to minutes.

Activity 3

Pair Work:

• Assign few questions to be done in pairs;

o   Convert the following into minutes: 2 hours, 9 hours, 15 hours and 20 hours

o   Just after the pair work on above is done, clear the board and write as below: if 60 minutes = 1 hour then 120 minutes = ……hours?  Let them think and respond]

o   Repeat this activity with few more examples.

• Take feedback and share correct answers with the whole class.[Repeat that division is the opposite of multiplication]

Activity 4:

Whole Class: [Minutes to seconds)

• Recall:

o   We have seen learnt to convert hours into minutes and minutes into hours.

o   Now we will change minutes to seconds? How will we do that? [Let them think and respond then write answers on the board]

• Now write on the board 1 minute = …… seconds [they will tell 60 seconds, discussed recently]
• Now write 2 minutes = ….. .seconds, [Few students will reply 120 seconds]
• Ask why and then conclude that for converting from greater unit to smaller unit we multiply [GSM}
• Ask few questions like 4 minutes, 14 minutes, 30 minutes will be equal to how many seconds [from the whole class]
• Ask what is the opposite of multiplication? [Division]
• Hence if we convert from seconds to minutes, [what do we do?] [Repeat the question if needed let the class come up with the answer i.e. DIVIDE]
• Write on board if 60 seconds = 1 minute then 360 seconds = …… minutes” [give few minutes and let them answer]
• Write few more questions on board to be done as whole class. For example, 120 seconds, 180 seconds, 420 seconds etc.

Activity 5

Challenge of the day:

• Let them discuss with each other, until the whole class is convinced on that Khurram takes longer time Along with reason.
• You may ask few students to explain it?

Activity 6

Individual Written Work:

• Write sums on the board and ask them to complete within the allocated time.
• Let them exchange their notebooks and check each other`s work.

Sum up / Conclusion

• 1 hour = 60 minutes
• 1 minute = 60 seconds
• To convert the hours to minutes and minutes to seconds we use GSM.
• To convert seconds to minutes and minutes to hours we user SGD.
• 24 hour clock show time from 00:00-24:00 so
• 12 hour clock show time in ‘a.m.’ and ‘p.m

Assessment

• How many hours are, there in a day? [24 hours]
• How many seconds are, in an hour? [3600 seconds]
• How many minutes are, in a day? [1440 minutes]
• How many seconds are, in 02 hours? [7200 seconds]
• How many minutes are, in a week? [10080 minutes]

Individual work

• Convert

I)                   45 minutes in hour?

II)                1 ¾ hours in minutes?

• Write the time from the following clocks;

a)      Time between noon and midnight.  

b)      Times are between midnight and noon. 

• Teacher must involve the student in solving the exercise questions given in the end of the lesson of textbook.

Follow up 

• Give questions from the textbook as well.
