1. "Arithmetic is being able to count up to twenty without taking off your shoes." -- Mickey Mouse
Set up powerpoint slide show
Draw Graph on board
Set up room graph
Pass out funny graphs (one per table)

3. Matching Quadrant I _____ Quadrant II _____ Quadrant III _____B C D
Quadrant I _____
Quadrant II _____
Quadrant III _____
Quadrant IV _____

5. Overview Types of graphs Parts of a line graph Interpreting Graphs
Reading graphs
Building graphs
Attendance sheet
Pass out graphs

6. Types of graphs Bar graph Circle graphs Line graphs
Shows comparisons of categories
Example 1 P. 160 (Demonstrate A, ask for B)
Demonstrate building bar graph (hate vs neutral vs like math)
Build bar graph – Where do you live
Demonstrate building graph with DOE table
Y axis 17K – 50K
Female then male
Circle graph (Or Pie chart)
Shows what percent of the whole that each item represents
Example 2 (p. 161) (Demonstrate A, ask for B)
Demonstrate building pie chart with math dislike data
Line graph
Example 3 (P. 162)
Demonstrate example 3a
Ask for answer to 3b
Show example 1 as a line graph
Funny bar graph
Funny circle graph
Funny line graph

7. Attendance vs Grade

8. Homework Points vs Grade

9. Change in Grade after Final Exam
Grade Increased
Grade
Decreased
Circle graph (Or Pie chart)
Shows what percent of the whole that each item represents
Example 2 (p. 161) (Demonstrate A, ask for B)
Demonstrate building pie chart with math dislike data

10. Points and Ordered Pairs
Graph or plot pairs of numbers
Two perpendicular axes
Origin
Coordinates
Ordered pairs
Example 4 – Plot (-3, 4)
Example 5
Show using room graph:
Axis/Axes – horizontal and vertical
Axes meet at the origin
To plot a point need the Coordinates show location along the axis – need two coordinates (horiz and vert)
Two coordinates are called Ordered pair (order is important)
Written (a,b)

11. Axes and Windows Scale x-axis/y-axis Quadrants
Scale (Room is scale of 1)(could make it 100, 200, 300 or 2,4,6)
Whatever will make the graph legible, readable, and uncluttered
National debt was over $9 Trillion in Sep 2007
Using graph paper with one square = $1, then 35,541,561 Miles high and would almost reach Mars when closest to earth
Could use larger scale where each unit is 1 trillion
Jagged break
but would be hard to plot even a billion dollar change, and lots of empty space
Could use jagged break and start scale at a higher number (debt in 2000 was about 5.6 trillion)
May have to do both (8,990 billion to 9,000 B)
x-axis/y-axis – Algebra uses x and y as variables a lot of the time
Show on room graph
Show Quadrants on room graph (who is in n quadrant?)

12. Interpreting Graphs Labels and units Relationships Trends Values
Maximums and minimums
P Use room graph to pick student to identify labels
Relationships (Instructor answers)
Trends (pick student)
Values (pick student)
Maximum and minimum (pick student)

13. Building line graphs Demonstrate with GHC annual headcount
x axis – 2001 to 2007
Y axis – 6,400 in scale of 200
