Segments That Meet at Right Angles
Can segments be considered perpendicular if they don't intersect? Learners look at nonintersecting segments on the coordinate plane and make conclusions about the lines that contain those segments. They determine if they are...

Lines in the Coordinate Plane
Young scholars graph lines in a coordinate plane. In this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They classify the lines as parallel or perpendicular and write an equation of a given line.

Iterating Linear Functions
Students use a spreadsheet to investigate data. In this algebra lesson plan, students collect and graph data on a coordinate plane. They explain properties of a linear equation both algebraically and orally.
