1. Metric Conversions DRUL Method

2. Warm-up: Writing Metric Terms
List as many rules for writing metric rules as you can think of in your notebook
Come up to the board and list your answers. If your answer is the same as another student’s place a check mark next to their answer.

3. Rules for writing metric terms:
Square the actual unit, not the measurement.
Use a 0 in front of the decimal point
Use a space between number and unit symbol
Don’t use plurals
No Fractions always decimals
When moving up go to the left and when moving down go to the right .
No periods at the end of a measurement

4. Metric System
Standard measurement system used in almost all countries and in science
Easy to convert measurements
Based on powers of ten
Convert by moving the decimal point (NO FRACTIONS!)

5. Units of Measurement
Unit Symbol What it Measures Meter m length Gram g weight Liter L volume Celsius C temperature
