Activity Title:                                                                                   Lesson
Predicting Trends                                                      Duration:        3 days
GLEs                       38. Sketch and interpret a trend line (i.e., line of best fit) on a scatter plot (D-2-M) (A-4-M)
39. Analyze and make predictions from discovered data patterns (D-2-M)

Mini-Lesson Procedure:
Objectives:
(list all that apply)
The student will sketch a trend line on a scatter plot.
The student will make predictions from discovered data patterns.
The student will create a PowerPoint presentation to demonstrate their knowledge of
scatter plots.

Procedures:

Essential Questions:
1. What is a scatter plot?
2. How are trends used to show a relationship?
3. What are some situations that would require you to study trends?

Trend Activity
Students will complete the daily problem. (Answers are in the binder.) After allowing 5 minutes for
students to complete the daily problem, slide will transition to discussion slide for discussion of daily
problem.
I. Pre-Assessment:
1. Preview the overview of the lesson so that students know what to expect. Have students read
each of the bullets aloud. (Relate this to the GLE(s) for the lesson.)
2. Using the inspiration slide, complete the KWL activity with the class.
 Topic- scatter plots
Let the students brainstorm and discuss orally what they know about scatter plots, (one
student will record results on chart paper), then discuss what they want to know, and then
after the lesson we will discuss what we have learned so that students may focus on this as
they work.

II. Powerpoint as a teaching tool:
1. View and discuss United Streaming video (Caribou and Gators) on scatter plots and trends.
a. Discuss the gator scatter plot with students. Teacher will pause video and discuss with students.
b. Discuss with students other examples of trend data.
2. Class will create a scatter plot together from the data given on the PowerPoint. (Guide the
students through this activity.)
3. Discuss trends with class. (Make sure the idea of positive and negative comes up.)
4. Assign group projects. Teacher will monitor student progress and ask probing questions so that
the slower groups gain the needed knowledge about trends.
5. CLOSURE: Students will complete an exit ticket as a reflection tool for student and teacher
feedback.
