GRAPHING DATA

6.EE.9 Use variables to represent two quantities in a real- world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable Objective: Understand how to graph two related amounts on the Cartesian Coordinate Plane Learning target: Answer at least 3 out of 4 coordinate plane questions on the exit ticket.

It lets us compare two amounts and see how they are related. For example, you could find the distance traveled in a certain amount of time. Review: Why is the coordinate plane useful?

The point is (3, 2). The x-coordinate of 3 means 3 hours. The y-coordinate of 2 means 2 miles. This means in 3 hours I went 2 miles. In 1 hour I went 2 miles. What does this mean? What does the point (1, 2) mean?

The point is (1, 2). The x-coordinate of 1 means 1 apple The y-coordinate of 2 means 2 dollars This means 1 apple costs 2 dollars. The Point is (4, 5). This means 4 apples cost 5 dollars. Explain the meaning of each point.

The point is (2, 6). The x-coordinate of 2 means 2 triangles The y-coordinate of 6 means 6 sides This means 2 triangles have 6 sides The Point is (5, 15). This means 5 triangles have 15 sides. Explain the meaning of each point. Warning: look at the numbers on the y-axis

First, label the x and y-axis with numbers and what they stand for. Put points on the graph by matching the x and y coordinates. Example: If something took 5 hours to go 1 mile x stands for hours, so since it took 5 hours, x = 5 Since y stands for miles, y = 1 since it went 1 mile Graph the point (5, 1) How do we graph data?

Label the axes Place a point at Game 1, 4 Points Place a point at Game 5, 2 points Graph: In Game 1 I scored 4 points. Graph: In Game 5 I scored 2 points

Graph: It takes 2 people to lift 1 box. OR

x (number of shots) = 5 y (points) = 4 We want the point (5, 4), which is D It took me 5 shots to score 4 points. Which letter should I put a point at?

x (number of workers) = 4 y (hours) = 3 We want the point (4, 3) If there are 4 workers, it will take 3 hours to complete the job. Which point would represent this?

x (number of books) = 3 y (dollars) = 5 We want the point (3, 5) which is A If you put D (5, 3), chances are you did not check the label of the x and y axes to see what amount each of them represented. It would cost 5 dollars to buy 3 books. Which letter should I put a point at?

x (number of apples) = 2 y (number of dollars) = 4 You needed to relate 2 apples and 4 dollars in some way. Example answers: 2 apples cost 4 dollars I sold 2 apples for 4 dollars 2 apples weigh the same as 4 dollars If there are 2 apples in a box, there will also be 4 dollars. Explain in a sentence what this point means.

Direct Station We will use whiteboards/Educreations to work with graphing multiple data points for a situation

Collaborative/Skill-Building Station You will be given a series of graphs. For each graph, you must write a sentence explaining the meaning of the point(s). To do this, look at what the x and y-axes stand for. Example: You write: This shows that 2 apples cost 4 dollars.
