The Linear Behavior module gives students experience in working with real-world data. Students will be able to read, organize, identify and interpret data that fits a linear model. Students will use technology to find the line of best fit. Lesson 1 Costs of Higher Education Using data about average salary and level of education, students learn to set appropriate scales for drawing graphs. Students use a strand of spaghetti to estimate the line of best fit.
Students investigate the relationship between slope, arithmetic growth, and common difference.
Lesson 3 Body Graphing Students physically act out being coordinates on a line. Students investigate intercepts, slope, parallel and perpendicular lines. A Business Venture Students investigate increasing and decreasing lines and zero and undefined slopes. Lesson 5 The Bouncing Ball Students collect data for use in examining linear behavior and making predictions. They learn to distinguish between dependent and independent variables.
