Investigating Inequalities (Grade 7)

In this lesson set, students extend their previous understanding of equations to include inequalities.  

Through engaging in the tasks in this lesson set, students will: 

• compare problem situations that can be solved with equations to problem situations that can be solved with inequalities; 
• compare the solution of an equation to the solution set of an inequality; 
• solve equations and inequalities using various methods; and 
• articulate why it is necessary to “switch” the inequality symbol when dividing or multiplying by a negative value.
