In this lesson, fifth graders learn to graph data using a coordinate grid. The teacher guides students through graphing outdoor temperature data and windows repaired data, emphasizing the importance of labeling axes and creating ordered pairs. Students are assigned homework to practice these skills and are encouraged to self-assess their understanding.

What is the essential question for Lesson 9.3?

• How do you measure temperature accurately?

• What is the importance of data collection?

• How can you use a coordinate grid to display data collected in an experiment?

• What are the different types of graphs?

What is the first step in graphing data from a table onto a coordinate grid?

• Calculate the average of the data.

• Draw the grid lines.

• Collect more data.

• Label the axes and create ordered pairs.

In the temperature data example, what does the x-coordinate represent?

• The origin point

• Time in hours

• Number of data points

• Temperature in degrees Fahrenheit

What is the y-coordinate in the temperature data example?

• The origin point

• Number of data points

• Temperature in degrees Fahrenheit

• Time in hours

What does the ordered pair (1, 61) represent in the temperature data?

• The temperature increased by 61°F in 1 hour.

• The temperature decreased by 1°F in 61 hours.

• At hour 61, the temperature was 1°F.

• At hour 1, the temperature was 61°F.

In the windows repaired data, what does the x-coordinate represent?

• Time in hours

• Temperature in degrees

• Total number of windows repaired

• Number of days

What is the y-coordinate in the windows repaired data?

• Time in hours

• Temperature in degrees

• Number of days

• Total number of windows repaired

What should be the title of the coordinate grid for the windows repaired data?

• Time Analysis

• Temperature Data

• Days Count

• Windows Repaired

How should the y-axis be labeled for the windows repaired data?

• Total number repaired

• Temperature

• Days

• Time

What does the ordered pair (2, 30) tell you about the windows repaired?

• 2 windows were repaired every 30 days.

• The repair rate was 30 windows per day.

• After 2 days, 30 windows had been repaired.

• 30 days were needed to repair 2 windows.
