The mathematics goal of this activity is to deepen students' understanding of solving linear inequalities by graphing.
At the end of a 90 minutes class, the students should be able to:
- Solve linear inequalities by using the TI-Nspire calculator;
- Solve real world problems by applying the concept of solving linear inequalities;
- Complete the group activity collaboratively; and
- Make a reflection about the concept learned for the day.
Before the Activity
Load LinearInequalities5.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.
During the Activity
See directions in the attached teacher document.
