In this packet you will learn what a unit analysis is and how unit analysis can be used. You will then learn how to solve problems with this new skill.
Unit Analysis- The process of using conversions between different types of units as a guide to solving a problem.
-a unit is a label on a quantity
ex: look for questions such as how much/ many, what is, or solve for to figure this out.
Conversion Factors- Different units of measure for the same amount.
ex: 1 meter= 100 centimeters
just a few examples...
100 pennies = 1 dollar 1 dollar = 100 pennies
1 mile = 5280 feet 5280 feet = 1 mile
1 foot = 12 inches 12 inches = 1 foot
60 seconds = 1 minute 1 minute = 60 seconds
100 centimeters = 1 meter 1 meter = 100 centimeters
4 weeks = 1 month 1 month = 4 weeks
etc, etc...
Using real-life situations to introduce conversion factors
