Product Description
Discover solutions to inequalities with this around the room activity called "Am I a Solution?"

Use this activity to allow students to experiment with possible solutions to inequalities. Students should think about what a solution to an inequality means and why it is a solution. This activity will help them do so!

Prerequisites:
Knowledge of inequality symbols
Ability to simplify expressions (Calculator use is optional, depending on ability)

Students do not need to know how to solve complex inequalities before this activity. I usually teach how to solve simple inequalities, and then students do this activity to discover how compound and absolute value inequalities work.

Prep:
Print and cut the 18 inequality cards (6 pages with 3 per sheet) Post these around the room.
(Optional) Print an inequality sheet for each student to show their work.
Pair students and assign each pair an x-value.

Activity:
Student pairs will visit each inequality card posted around the room. At each card, they will plug in their assigned x-value to determine if it is a solution to the inequality. They will write their x-value in the appropriate box (Solution or Not a Solution). Then, they will mark their x-value on the number. If it is a solution, they should mark a closed circle. If their x-value is not a solution, they should mark an open circle on the number line. Rotate and repeat at each card.

After every card has been visited (or several rotations as time allows), each pair of students takes one inequality card and tries to determine all the possible solutions, based on what other students have marked as solutions or not.

This should lead to a great discussion about solutions to inequalities within pairs.

The activity does not teach students the actual procedure for solving compound and absolute value inequalities. At this point in the lesson, I teach students the actual procedures. Then, they revisit their inequality sheets and solve each one.
