Have students review their notes and learn the function of each key discussed.
Teacher Notes
The first day is very important in setting the tone for the classroom. Be sure to explain school
policies regarding the appropriate use of graphing calculators (i.e., policy for checking out/in
calculators, playing games, etc.).
It is important to let the students have unstructured time with the calculators at first. Students
will be so involved with the technology that they probably will not focus on any specific task
initially.

follow along silently. Answer any questions the students may have. Assign students to groups
using a method from Appendix B and monitor activities.
Have the students note the following:
Scatter plot: a graph that shows the relationship between two sets of data plotted as ordered
pairs.
Line of best-fit: A line on a scatter plot that comes as close as possible to the data points.
Correlation: The relationship between two sets of data.

Teacher Notes
1. Check that the students are in groups of at least five.2. Tape two or more yard sticks to an object in the room. Place the yard sticks 20 cm above the
floor. This will make measuring height easier for the students.
3. Encourage all of the students to participate.4. Remind students that line of best-fit should:a) show the direction of best-fitb) divide the points equallyc) have as many points as possible on the line

Guidelines for Activity 1
1. The groups should be composed of at least five people.
2. One person from each group will secure and return all materials.3. Take turns measuring and recording the information.
4. Double-check and verify all measurements before recording the information.
5. Prepare a report on group Activity 1.
6. One person from each group will present his/her groups report to the class.
ACTIVITY 1
1. Measure and record the wingspan in centimeters of each person in your group. (wingspan -
from tip of middle finger of left hand to tip of middle finger of right hand)2. Measure and record the height in centimeters of each person in your group.
3. Using graph paper, plot your data.
4. On the horizontal line, indicate the height. On the vertical line, indicate the wingspan.
Note: Although we can put the height on the vertical line, we wish to predict your wingspan.
wingspan
height
5. Place your data (ordered pairs) on the group chart paper in the front (or back) of the room.
6. Plot on one graph the data from all the groups. (This graph is called a scatter plot.)
7. Suppose a student is 175 cm tall. Use your graph to predict the students wingspan. Use the
graph of the groups to predict the students wingspan.
8. Continue with Activity 2.

Guidelines for Activities 2 & 3
1. The groups should be composed of at least five people.
2. One person from each group will secure and return all materials.3. Take turns measuring and recording the information.
4. Double-check and verify all measurements before recording the information.
5. Prepare a report on Activities 2 and 3.
6. One person from each group will present his/her report to the class.
ACTIVITY 2
1. Repeat steps 1-6 from Activity 1, using your foot size and forearm measurements incentimeters.
2. On the horizontal line, indicate the foot size. On the vertical line, indicate the forearm length.Note: This graph is also a scatterplot.
3. Suppose a student has a foot size of 30 cm. Use your graph to predict the students forearm
length.
Use the graph of all the groups to predict the students forearm length.
ACTIVITY 3
1. Using your graph from height vs. wingspan, use a ruler to sketch the line that you think best
approximates the data points.
2. Locate two points on the line (one near the top of the line and one near the lower end of the
line) and approximate thexandyvalues of each point. (The points do not have to be two of
the original points.)3. Use the slope-intercept form of an equation to find the equation of the line that passes
through the two points you just found.
Note: The line you are approximating is called theline of best-fit.
