# Lesson 15

Shapes on the Coordinate Plane

### Lesson Narrative

In this lesson, students apply their understanding of rational coordinates and distance in the coordinate plane to construct polygons and navigate a maze. Students plot coordinates in all four quadrants and find horizontal and vertical distances.

### Learning Goals

Teacher Facing

• Determine the total length of multiple horizontal and vertical segments in the coordinate plane that are connected end-to-end.
• Draw a polygon in the coordinate plane given the coordinates for its vertices.
• Explain (orally) that coordinates can be a useful way of describing geometric figures or modeling real-world locations.

### Student Facing

Let’s use the coordinate plane to solve problems and puzzles.

### Required Preparation

Provide students access to graph paper and colored pencils for the lesson synthesis or upon request during the lesson.

### Student Facing

• I can find the lengths of horizontal and vertical segments in the coordinate plane.
• I can plot polygons on the coordinate plane when I have the coordinates for the vertices.
