Lesson Title: Off Road Math Teachers: Mrs. Stephanie Brandyberry (Primary) Brief Description:
The lesson teaches students about an important characteristic of lines: their slope. Slope can be determined either in graphical or algebraic form. Slope can also be described as positive, negative, zero, or undefined. Students get an explanation of when and how these different types of slope occur. Finally, students learn how slope relates to parallel and perpendicular lines. When two lines are parallel, they have the same slope and when they are perpendicular their slopes are negative reciprocals of one another.
Topics Introduced:
slope, gradient, equations of lines
Transportation, Distribution, and Logistics Curriculum Framework Components Addressed:

Science, Math, Engineering and / or Technology Implications:
Because many important engineering applications can be better described by a graph of their lines, students need to understand important characteristics of those lines. One of the most descriptive characteristics of a line is its slope, so students need to know about this aspect of lines.
