This Instructional Activity is a part of the Lesson 9, Unit 7, Grade 6. This activity has been made optional for time considerations. The purpose of this activity is for students to reason about whether given values make an inequality true and justify their answers using inequality statements and graphs. Students explored this concept in the previous activity, so they should work to articulate how they check if a number is a solution to an inequality statement and an inequality on a number line. Students will play a game to practice this skill. The game's goal is for one student to guess a mystery number using as few inequalities as possible.
