Stories about 9

This Instructional Activity is a part of the Lesson 8, Unit 7, Grade 6. In this activity, students extend their understanding of inequality statements by considering an unknown quantity with one or more constraints in a real-world situation. Students represent situations with inequality statements and reason about possible values that make them true, showing the possibilities on a number line. They realize that these situations often have many values that make the inequality true, and often even an infinite number, making the number line representation of possible values very useful.
