Class/Group Activity - Write Inequalities from Conceptual Problems

This is a group/class activity for students to practice writing multi-step in inequalities. There are 4 problems with 5 possible answers each. More than one inequality may be correct. Students will discuss their choices and then must be ready to defend their answers.

This activity corresponds to the Common Core math standard: CCSS.MATH.CONTENT.7.EE.B.4.B Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem.

Teacher Directions Before Lesson: Divide students into 6 groups. Assign each group a letter A – F. Cut apart inequalities. Make a “yes” box and a “no” box. If you don’t have a document camera, then copy the questions to a Power Point to display to class. (or copy to overhead sheet to display)

Lesson: Have students move their desks to groups so they are able to discuss and hear everyone in their group. Give each group their corresponding inequality for #1 while placing question #1 where the class can read. Each group will decide if their inequality is correct or not and then place the inequality in the correct yes or no box. When everyone is ready, go over each inequality by having each group explain their decision. Continue in the same way for the remaining questions. You might want to make it a game and keep score.
