Graphing calculators are used both to build concepts and as a tool. The teacher notes contain content background, suggestions for presentation, and problem solutions. For each activity students are given problems to solve and directions for their investigation and ensuing discussion. In a sample activity, students determine if there is any relationship between the total points scored by players in a basketball game and the time spent on the bench. Students use information from a data set and a graphing calculator to construct a scatter plot for the two variables.
Students discuss and write a paragraph to describe the relationship between the variables.
In the extension, students plot the relationship between total points scored and playing time in a 20 minute game. Students look for similarities and differences between the two graphs. A glossary is included. ENC does NOT distribute this resource.
