There are many problems throughout the text labeled IN YOUR OWN WORDS.
Just relax. Do not be afraid to give your opinion. For the most part,
these questions do not have "right" or "wrong" answers. You should spend
about five minutes in answering each of these questions. "For Problem
1 you might want to check the first link listed below.
For this chapter, you will need to know the abbreviations for the various
units of length. You should try to remember these.
These are estimation problems. Do not answer these questions by direct
measurement. The point with these problems is to develop your intuition
with the standard units of length.
You should learn the metric prefixes: kilo (times 1,000); hecto (times
100); deka (times 10) deci (times 1/10); centi (times 1/100); milli (times
1/1,000) The important idea of this section is to help you to THINK in metric.
Do not attempt to convert from the metric system to the U.S. measurement
system. Don't be tempted to use a ruler to be "right" but rather make an
attempt to estimate these lengths.
See Examples 1-3.
Here you must think in another unfamiliar unit of measurement. It is
important to practice THINKING in different measurement systems.
Even if this problem is not assigned, it is a worthwhile problem because
it can give you some reference points for linear measurements. The importance
of the problem is not what you write on paper, but what you remember. If
you don't remember your measurements, then you will not have an easy
reference system for THINKING METRIC!
