The document discusses measuring length and the importance of standardized units of measurement, highlighting the historical context of nonstandard units based on body parts. It details the two major systems of measurement—English and Metric—with specific conversion methods for units such as millimeters, centimeters, meters, and kilometers. Additionally, it encourages self-directed learning and application of mathematical skills related to length conversions.

1. Measuring Length
and Conversions
Linear Measurements

2. Life Performance Outcome
I am a mindful, self-directed learner and role
model, consciously expressing my Faith.

3. Essential Performance
Outcome
Have the initiative to seek and learn new
mathematical skills, then apply them on their
own.

4. Intended Learning Outcome
Have the initiative to visualize, represent, and
convert common units of measure from larger to
smaller units and vice versa, then apply them on
their own.

5. TAKE A LOOK Back!
A long time ago, the Babylonians, and Egyptians' standards of measurement
were based on body parts (digit, palm, span, cubit, foot). These are examples
of nonstandard units. But people have different sizes of body parts. So, to
avoid confusion, there was a need to have the same standard of
measurement.

6. Table of Conversion- English System
12 inches= 1 foot
3 feet= 1 yard
1760= 1 mile
5280 feet= 1 mile
1. English System
There are two major systems of standard
measurement that we use:

7. Table of Conversion- Metric System (SI)
Length
1000 millimeters (mm)= 1
meter
100 centimeters (cm)= 1 meter
1000 meters (m)= 1 kilometer
(km)
2. Metric System
There are two major systems of standard
measurement that we use:

8. Measuring Length in the
Metric System
•Length in the metric system is measured in
millimeters, centimeters, meters, and
kilometers for long distances
* Kilometers are used for long distances; for example, distances traveled by a car, the distance one runs in a
marathon or when jogging, the distance between two cities, and more.
