The PPT is designed for the Math teacher to teach about the unit system and length as an Individual parameter for standard 3rd to 10th. First, inspire the curiosity of students by showing images instead of directly introducing the topic. To make the live presentation better ask various questions to students like -Where else you see the application of measurements? -How and who invented it? -Which unit we use for a particular purpose and where? and more. This ppt includes, Learn unit conversion easily with a smart trick. Understand the SI unit and Imperial unit system. The value of each unit as well with practice sum. Mainly focus on the length and its unit.

3. Guess the topic…..

4. Measuring
Length and Distance

5. It is said that long, long ago, people used the length of the king’s
foot to settle arguments about how long or wide something was.
So that everyone would know how long his foot was, the king
passed out sticks the same length as his foot. The sticks were called
the ruler’s foot or “rulers.”
Activity-1

6. Problems
• It would often change as soon as a new king
was crowned
• It was different from country to country
Which is a basketful?

7. LENGTH MEASUREMENT
standard units.
Millimetres (mm)
Centimetres (cm)
Metres (m) Kilometres (km)
• When we measure
length, we measure
how long something is.
• A whole system of
measurement was
developed with the
meter as its basis.

8. SI system
• (metric system) – a
standard unit of
measurement
All scientists everywhere
can share and replicate the
same data. Now used in
nearly every country in the
world except the United
States.
1790
What is the Metric
System?
• There is only one base
unit for each thing
measured
Length = meter
Mass = gram
Volume = liter

9. 6 common prefixes:

10. Kilo-
• Symbol = k
• Number = 1000
kilometer kiloliter kilogram
1000 meters 1000 liters 1000 grams

11. Hecto-
• Symbol = h
• Number = 100
hectometer hectoliter hectogram
100 meters 100 liters 100 grams

12. Deka-
• Symbol = da
• Number = 10
dekameter dekaliter dekagram
10 meters 10 liters 10 grams

13. Meter, Liter, Gram
• Symbol = m, l, g
• Number = 1
meter liter gram
length volume mass or weight

14. Putting the 2 symbols together
• Kilometer = km
• Hectogram = hg
• Kiloliter = kl
Kilo = k meter = m

15. Deci-
• Symbol = d
• Number = .1 (tenth)
decimeter deciliter decigram
.1 meter .1 liter .1 gram

16. Centi-
• Symbol = c
• Number = .01 (hundreth)
centimeter centiliter centigram
.01 meter .01 liter .01 gram

17. Milli-
• Symbol = m
• Number = .001 (thousanth)
millimeter milliliter milligram
.001 meter .001 liter .001 gram

18. Practice
• If I give you the symbol, you give me the prefix
h =
c =
d =
m =
da =
k =

19. Practice
• If I give you the prefix, you give me the number
kilo =
deka =
milli =
hecto =
deci =
centi =

20. Practice
• If I give you the symbols, you give me the word
mg =
hm =
dal =
cl =
km =
dg=

21. Metric (SI) vs Imperial
The European UnionUnited States

22. Different measuring tools
Activity-2

29. Try some by your own
1. 3 km= _____________M
2. 5000M=____________km
3. 100mm=___________cm
4. 67M=_____________cm
5. 12 mm=____________M

30. Research work
• How “Meter” was founded?
• Try to measure the length of different objects at your home
in inches, mm, cm and M like TV screen, Your bad, Tiles,
Door.
