The mathematics goal of this activity is to deepen students' understanding of solving systems of linear equations by graphing.
At the end of a 90 minutes class, students should be able to:
- Graph the two given equations simultaneously using the TI-Nspire graphing calculator;
- Give the coordinates of the point of intersection;
- Solve real world problems by applying the concept of solving systems of linear equations by graphing;
- Complete the group activity collaboratively.
Before the Activity
Load VideoRental3.tns file onto all the students' handhelds. The activity consists of a problem designed to be teacher directed with time for students to investigate and record their observations.
