Geometry Module 4: Connecting Algebra and Geometry Through Coordinates

In this module, students explore and experience the utility of analyzing algebra and geometry challenges through the framework of coordinates. The module opens with a modeling challenge, one that reoccurs throughout the lessons, to use coordinate geometry to program the motion of a robot that is bound within a certain polygonal region of the plane—the room in which it sits. To set the stage for complex work in analytic geometry (computing coordinates of points of intersection of lines and line segments or the coordinates of points that divide given segments in specific length ratios, and so on), students will describe the region via systems of algebraic inequalities and work to constrain the robot motion along line segments within the region.

The student materials consist of the student pages for each lesson in Module 4.

The copy ready materials are a collection of the module assessments, lesson exit tickets and fluency exercises from the teacher materials.
