In this TV411 activity, students learn to associate simple fractions of wholes with equivalent percentages in the context of basketball scores and stadium capacity. The video clip, the handout, and Assessment A focus on 25%, 50%, 75%, and 100%, while Assessment B extends to 20% and multiples.
Percentages in Basketball QuickTime Video
Part I: Learning Activity
1. Read the following to your students: "You will watch a video clip in which Nancy Lieberman and Lynette Woodard of the WNBA's Detroit Shock discuss how popular women's basketball has become. They know the crowds have been running at about 50% capacity of the stadium, which holds 22,000 fans. They set a goal to reach 75% capacity. On a sheet of paper, try to figure out how many more people they would need to attend to meet their goal."
2. Discuss the students' approaches.
3. Watch the Percentages in Basketball QuickTime Video . Tell students to watch how the players solve the problem.
4. Distribute the Visualizing Percents Handout .
5. Ask students to work on the handout in pairs.
6. Discuss the handout. Make sure the students pay attention to the different number of fans that represent the whole capacity of the football stadium in the handout.
Part II: Assessment
Assessment: Level A (proficiency): Students practice both identifying 2-D coordinate points that are plotted for them and plot points when given pairs of coordinates.
Assessment: Level B (above proficiency): Students apply their knowledge from the Cyberchase video clip to see if the three lines given will intersect.
