Lesson Planning of Conversion of Units of Lengths (Km into M)
Subject Mathematics
Grade 4^{th}
Students` Learning Outcomes
 Convert Milometers into meters and vice versa.
Information for teachers
 Kilometre and meter are units of measurement and can be written as km and m respectively.
 Kilo means one thousands, therefore kilometre means one thousands meters.
 Kilometre is used to express distance between cities and countries in most of the world except United States and the United Kingdom.
 1 kilometre = 1000 meters
 Multiply kilometres with 1000 to convert them into meters (Meters = km x 1000)
 Divide meters by 1000 to convert them into kilometres (km = m/1000)
 During this lesson, the teacher should also consult textbook at each level where required.
Material / Resources
Writing board, chalk / marker, duster, measuring tape, meter rod, scale, flash cards, textbook
Introduction
 Tell the students that today we will learn how to convert kilometres and meters into each other.
 Tell them that hundreds of years ago, people used stones, wooden pieces, bones, hands and feet to measure.
 Ask the students have they ever heard about ‘kilometre and meter’? (Share with class)
 Give some daily life examples related to the topic, as; length of cricket bat is normally equals to a meter.
 Unit ‘kilometre’ is used to measure distance between two cities, as; Lahore is 425 km far from Bahawalpur.
 While buying cloth for you, your parents normally use word “meter” e.g. 6 meters cloth.
Development
Activity 1
Conversion from meters into kilometres:

Activity 2
5.7 km = 5700.0 or 5700 m 5.72 km = 5720.0 or 5720 m 15.72 km = 15720.0 or 15720 m
2.3 m = 0.0023 km 2.36 m = 0.00236 km 22.36 m = 0.02236 km 
Sum up / Conclusion
 Finish the lecture by revising the key points of today`s lecture so students can recall what they have learnt.
 Tell them as; 1 km = 1000 m
 Kilometres can be converted into meters by multiplying with 1000, as m = km x 1000.
 Meters can be converted in kilometres by dividing with 1000, as; km = m/1000.
 In decimal numbers to convert meters into kilometres move the decimal point 3 places left., as 2.5 m = 0.0025 km.
 In decimal numbers to convert kilometres into meters move the decimal point 3 places to the right, as; 3.7 km = 3700.0 m or 3700 m
Assessment
 Spread four flash cards having kilometres written on them on the table.
 Call four students one by one and ask them to pick the flash cards.
 All the four students will turn wise show their cards to the whole class.
 Spread four more flash cards on the table having written meters on them related to the kilometres on previous cards.
 Ask them as you have already learned about conversion of units of measurement, so pick the relevant card of meters.
 Encourage the students for correct answer.
 Solve the following.
Follow up
 Assign following types of questions to the students as homework. Encourage correct answers and guide them if they produced wrong answers.
 The distance between mosque and school is 5 km. convert this distance in meters.
 Karachi express train covers 60000 m in one hour. Can you convert this distance in kilometres?
 My family is moving to a new house. Our old house is 3 km from the new house. How many meters is the old house from the new house?
 The fence around Bono’s garden is 360 m long. How much is the length of the fence in kilometres?
 The teacher should involve the students to solve the exercise questions given at the end of the unit/chapter.
