Lesson Planning of Conversion of Units of Lengths (Km into M)
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
- 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.
Conversion from meters into kilometres:
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
- 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.
- 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.
