| Inequalities on the Number Line|
In this Desmos activity, students explore linear inequalities and make connections among multiple representations (including algebraic expressions, verbal statements, number line graphs, and solution sets). There are a series of 3 videos available to fully teach this concept. The videos are labeled "Inequalities on the Number Line," "Compound Inequalities on the Number Line," and "Absolute Value Inequalities on the Number Line." This activity should be used to help teach a lesson on solving linear inequalities. This Desmos activity offers sample student responses and a teacher guide.
17 ) Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters. [A-REI3]

Desmos's mission is to help every student learn math and love learning math. Teachers can explore and enjoy Desmos collections of free digital math activities that include:
- Meaningful feedback by showing students what their answers mean, then give them the opportunity to improve their thinking and revise their work.
- Collaboration by using devices to connect students, not to isolate them. Students see their classmates' thinking. They ask each other questions and create challenges for each other.
- Invite students to solve challenging problems using the tools they already have.
If the teacher does not have an account, he/she will need to create a FREE account. (More information on how Desmos works can be found at Getting Started.)
Once the teacher has selected an activity to run, he/she will need to click on the "Create Class Code" button. This will generate a unique class code and a link to view the dashboard. (More information can be found at Creating a Class Code.) Every new activity will need a new class code in order to start a session. Students cannot start the activity until they have the class code so sessions can be started days, hours, or mere minutes before the teacher plans to run the activity. When the teacher is ready to have students start, have the students go to student.desmos.com and enter the class code. Although it is not required, Desmos strongly encourages students to sign in with their Desmos Student Account. Signing in allows students to resume and view their past activity work.
