Title – Basketball Probabilities II
By – Kevin Laws
Primary Subject – Math
Grade Level – 6th Grade
Topics: Percents and Predicting outcomes
Standards Addressed: NCTM Goal 4, 6th Grade
General Goals: Students will be able to find percentages given a set of data and predict outcomes.
Required Materials: Set of data collected in Basketball Probabilities and a Calculator.
Anticipatory Set: Discuss with the students some of the good and bad shooters in the NBA or college basketball. Examples: Reggie Miller, Michael Jordan, Lebron James, JJ Redrick, Shaquille O’Neal. Talk about their free throw and field goal percentages for a season. This information can be found at www.espn.com . Talk about how these percentages are calculated for a game and then for a season. Based upon this information, can we predict when one of these players goes to free throw line, whether they will make or miss their free throws?
Step by step procedure: Using the data collected in the previous lesson “Basketball Probabilities” have the students use a calculator to find the percentages (show how to find the percent using a calculator) for each student, each group, and then for the class. Based upon this information can we predict the number of shots that each shooter, group and class will make the next time we go to gym and shoot. Take the students back to the gym and have them shoot again. Each group needs to record the number of shots made from the free throw line out of 10. Each group should report to the teacher with their results. Record results on an overhead transparency. Report back to the classroom and let the students determine if their predictions were correct. Discuss with the students reasons why the information may have changed and how percentages change over time. You could have students find their percentage for both times that they shot.
Independent Practice: Find a box score in the newspaper from a college or NBA game. Have the students find the free throw, field goal and three point percentages for each player on a team and then the teams’ percentages.
