1. Metric System
based on a base unit that corresponds to a certain kind of measurement
Length = meter
Volume = liter
Mass = gram
Density = grams per cm³ or g/cm³
Prefixes + base units make up the metric system
Example:
Centi + meter = Centimeter
Kilo + liter = Kiloliter

2. PREFIXES are based on powers of 10.
each prefix is a step either:
10 times larger (left) or
10 times smaller (right)
examples
Centimeters are 10 times LARGER than millimeters (1 step)
1 centimeter = 10 millimeters
Hectometers are 10 times SMALLER than kilometers (1 step)
10 hectometers = 1 kilometer
Kilo

3. You do this no matter WHERE you begin on the scale
Movement within the metric system is done by moving the DECIMAL POINT one place for each “step” desired
You do this no matter WHERE you begin on the scale
Example to right: move to right to change from meters to millimeters
1.0 meter = millimeters
Example to left: move to Left to change from liters to kiloliters
1.0 meters = .001 kilometers

4. Metric System
Summary
Base units in the metric system are meter, liter, gram
Metric system is based on powers of 10
For conversions within the metric system, each “step” is 1 decimal place to the right or left
converting to the right, moves the decimal to the right and converting to the left moves the decimal to the left

5. GRAPHING- 3 Types of Graphs
-BAR GRAPHS -LINE GRAPHS
-PIE CHARTS

6. LINE GRAPHS
-A type of graph that highlights trends by drawing connecting lines BETWEEN data points.
What Every Line Graph should have!
-Axes (x,y) labeled
-equal intervals
-origin
-units
-title
-data points
-key (if needed for multiple variables)

7. -key (if needed for multiple variables)
BAR GRAPH
a type of graph where different values are represented by rectangular bars.
What Every Bar Graph should have!
-Axes (x,y) labeled
-equal intervals
-origin
-units
-title
-data points
-key (if needed for multiple variables)

8. PIE CHART
A type of graph where percentage values are represented as proportionally-sized slices of a pie.
What does every Pie Chart Need
Title
Explanation of sections (pie pieces)
Key if necessary
Different colors or patterns
Circle divided in percentages
