Semester Exam Study Guide, problem numbers ________ - _________.
Prior Knowledge
 Last time we met, we learned about function tables.
 Function tables are often referred to as input/output tables… With “x” being the input… and “y” being the output.
Anticipatory Set
 TODAY, we’ll learn how to graph data from a function on what’s called a coordinate plane. Once we graph the points, we’ll
determine the shape of the graph as a Straight line, a U-shape, a V-shape, or an S-shape!
 Before we get started…
 Let’s do a little “Treasure Hunting!”
 Display “Pirates!” (PowerPoint)
Teacher Input
 Review Bellwork
 Review Homework
 Explain the different parts of the “coordinate plane”.
 Explain and demonstrate how to name the (x, y) coordinates of a point on the graph.
 Explain and demonstrate how to graph a set of points on the coordinate plane.
 Explain: To graph a function, you must have a list of ordered pairs.
Once graphed the points will form one of these shapes (show transparency):
Straight line
U-shape
V-shape
S-shape (curve)
 Allow students to work the you-try problem independently.
 Classwork: BD 83 & BD 84 (Think, Pair, Share), then GL 36 if time.
Extra Practice: Students may begin their homework.
Assessment
Question students for understanding. Observation students as they work on their classwork. Assess skill on semester exam.
Closure
Beach Ball Math………
 What’s the definition of a pirate? Answer: A person who robs at sea.
 What was the name of a famous pirate? Blackbeard, Captain Kidd
 In which sea did most of the pirate attacks occur? Caribbean Sea
 Who discovered the Caribbean Islands? Christopher Columbus
 What began piracy? The pirates wanted the gold and silver fond in the New World.
 What were the ships called that hauled the gold and silver? Galleons
 What was the flag called that the pirates flew on their ships? The Jolly Roger
 What trick did the pirates use to attack their enemies? Flew a Spanish flag, then raised
 What is the starting point on the Coordinate Plane? Origin
 How many Quadrants are there? 4
 When naming an Ordered Pair what comes first… the x or the y? the “x”
the Jolly Roger.
Student Notes
10-1 Coordinate Plane
Textbook 486 - 489
New Vocabulary:
A
is formed by the intersection of a horizontal number line
called the x-axis and a vertical number line called the y-axis.
Labeling the Coordinate Plane:
X-Axis
Y-Axis
Origin
Quadrants
Ordered Pair
Horizontal number line___(line that goes across)_________________
Vertical number line_____(line that goes up and down)_____________
The point where the x-axis and y axis intersect. (Starting Point!)
_
The coordinate plane is divided into 4 quadrants which are identified
by the Roman Numerals I, II, III, IV._______________________
Gives the location of a point…… (X, Y)_________________________
What are the coordinates of:
Point J
Step 1: Start at the ORGIN and locate the x-coordinate.
Step 2: Locate the y-coordinate.
-2
Step 3: Write the points as an ordered pair. J (-5, -2)

What are the coordinates for Point K? Answer: (____, ____)
What are the coordinates for Point L? Answer: (____, ____)
Quadrant: ____
Quadrant: ____

You Try!
Start at the ORGIN
Move 3 units to the right along the x-axis.
Then move 5 units down along the y-axis.
Draw a “point” and label it “A”.
Label Point B (-4, -2)
Label Point C (3, 6)
Label Point D (3, 0)
Label Point E (0, 5)
What Quadrant is the point in?
_____
What Quadrant is the point in?
_____
Not in a Quadrant because it’s on the _____ axis.
Not in a Quadrant because it’s on the _____ axis.
