Students learn to design data investigations, describe data, and draw conclusions. They learn to choose the best type of graph, graph and interpret the data, and look for patterns and trends. They also use the calculator to investigate and communicate results.

Before the Activity

See the attached PDF file for detailed instructions for this activity

Print pages 63 - 83 from the attached PDF file

During the Activity

Distribute the pages to the class.

Follow the activity procedure:
Activity 1: Can You Improve Your Record?

Select a physical activity (bouncing a ball, hitting a target) that can be counted and recorded to measure performance

Gather data over a period of 5 days with 7 trials per day

Tabulate and analyze the performance scores, look for patterns of improvement, and graph the data on paper and on the calculator

Explore the different forms in which the trials can be graphed on the calculator (pictograph, bar graph, Box and Whisker plot)

Examine the mean, mode, median, and average values

Examine the data numerically and visually to interpret data and draw conclusions

Activity 2: The Timed Walk

Select a distance and have students walk back and forth in exactly 30 seconds

Conduct 7 trials per student and collect data

Record the time taken and note the deviation from the goal of 30 seconds

Plot the total trial data for each student and the difference of each trial from the goal of 30 seconds for all the 7 trials

Understand the meaning of the graph and learn to relate it to the speed, distance, and time of the walk

Activity 3: How Many Pages

Use a book with more than 100 pages and pick a number

Open the book as close as possible to the page corresponding to the number chosen

Record the number of pages they are away from the given number

Conduct 7 trials and observe patterns in the data

Predict the result of the next 7 trials and make a list of data of first trials and the predicted trials

Graph both data side by side and compare results

Assess the student's ability to collect, analyze, graph, and interpret data

After the Activity

Review students results and re-teach concepts as necessary.
