Math I: Move the Cone: Creating Linear Equations
Overview
Students are given 5 random coordinate points and must create a path of linear equations to navigate the rover around each point. Teachers can have students calculate the slope, y-intercept, domain and range of the lines. Students will calculate the distance of each line and find the total distance the rover travelled. Students will then be challenged to minimize the distance the rover travelled.
Teachers can extend this to include angles and distance, where the students calculate the angle the rover should turn and then the distance it should drive to go around each point.

Project Outline | |
| Ask | Students will create and write linear equations, with restricted domains, to create a path around scattered coordinate points |
| Imagine | Students will draw their path on paper and identify their potential endpoints to use and estimate the distance the rover will travel. |
| Plan | Students will then begin calculating the features of their equations, including slope, y-intercept, and domain.Or students will then calculate the angle the rover will need to turn and distance it will travel |
| Create | Students will make a list of the endpoints, calculate the key features of their lines and write their equations. Then begin programming the rover to draw the lines. |
| Improve | Students will be challenged to minimize the distance the rover travels to move through their points and end the path by moving the cone to the designated spot. |
| Closure / Student Reflections | Students will reflect on how the key features are related to the endpoints of the lines, and how the distance is affected by changing the features of each line. |
| Possible Modifications / Extensions | Teachers could add restrictions to make the task more challenging, including requiring the students to include a pair of parallel or perpendicular lines. |
