This document provides information about measuring distance using standard metric units. It discusses why measuring distance is important, the two main measurement systems, and focuses on the International System of Units (SI or metric system). Key points include that the metric system uses multiples of ten as prefixes for units of measurement. The base units for length, mass, time and other quantities are defined. Examples show how to use the "ladder method" to convert between metric units like centimeters to millimeters. Students complete practice problems converting between units of distance.

2. Pass The Message
 In the game, a message is given to
the first person in a line of people
and then they are instructed to
pass the message on by whispering
it in the ear of the next person in
line.

3. Gallery Walk
 List some locations that are
about 1 km from their school.

6. Why Learn to Measure?
Valuable skill for a job
Valuable skill for hobbies
Valuable skill for every day life

7. Measurement Systems
Two types of measurement systems exist.
 Standard (Customary)
- Metric (SI or International System)

All metric units are based on multiples
of 10. As a result, you can convert
between units easily.

 The metric system was originally
established in France in 1795.
 The International System of Units
(abbreviated SI after the French name,
Le Système International d’Unités) is a
revised version of the metric system.

 In SI, the basic unit of length, or linear
measure, is the meter (m).
 For very large and very small lengths,
however, it may be more convenient to
use a unit of length that has a prefix.

12. What do we measure?
 Fundamental properties
 mass (weight) kilogram
 length meter
 time second
 temperature Kelvin
 Derived quantities
 density, velocity, force, etc...

13. Using the metric system
 In the metric system, prefixes are used
to identify the multiples of ten.
 103 102 101 1 10-1 10-2 10-3
 Kilo Hecto Deka BASE Deci Centi Milli
Base units
 mass gram(g)
 length meter (m)
 liquid volume liter (l)
 time second (s)
Each multiple is one decimal place.

Ladder Method
How do you use the “ladder” method?
1st – Determine your starting point.
2nd – Count the “jumps” to your ending point.
3rd – Move the decimal the same number of
jumps in the same direction.
4 km = _________ m
