Content:

Putting our new knowledge of scatter plots to use.

Benchmarks:

D.AN.07.04 Create and interpret scatter plots and find the line of best fit; use and estimated line to answer questions about the data.
4.b.1. Students create a project (e.g., presentation, web page, newsletter, information brochure) using a variety of media and formats (e.g., graphs, charts, audio, graphics, video) to present content information to an audience.

Learning Resources and Materials:

• Worksheet with a blank chart and a blank scatter plot.

Development of Lesson:

Introduction:

The previous lesson “Making Scatter Plots” is the introduction to this lesson.

Methods/Procedures:

1. The class will be divided into groups.
2. If available, we will go into the gym or to an outside basketball court. Each group will be assigned to a basketball hoop. The number of groups will correspond to the number of hoops available.
3. Each group member will be given five turns to make a basket, each turn taking a step away from the basket. (These increments should be marked on the floor to make everyone equal.)
4. The groups will record in their chart, how many people make baskets at each distance.
5. Then, back in the classroom, the groups will input their data into Microsoft Excel and turn it into a scatter plot.
6. Observing their data, they will make observations about the trend(s).
7. Finally, we will compare our results as a class.

For my two students with Down Syndrome, I will work with them personally to record their results. They will get a smaller net and a chance for one-on-one learning.

Assessment/Evaluation:

The group presentations will be graded.

Closure:

In our final test on graphing, there will be a section on scatter plots. Performances on this test will prove how well the students have absorbed this material and whether or not these lessons have been effective.

Worksheet:

Name _________________________________ Hour ___________ Date __________________

Group Number _______ Group Members ____________________________________________

Directions:

1. Record each group member’s name the spaces provided below.
3. Complete the scatter plot below with the appropriate labels.
