Graphing Linear Inequalities Activities & Games

Instructor: Heather Jenkins

Heather has a bachelor's degree in elementary education and a master's degree in special education. She was a public school teacher and administrator for 11 years.

Graphing linear inequalities is important for students to visualize how inequalities work. Consider using these engaging, hands-on games and activities to help students learn about graphing linear inequalities.

Not Equal

Sometimes math doesn't always lead us to an exact answer. Sometimes there are multiple answers that are correct. When students learn how to graph linear inequalities, they can begin to discover the range of mathematical operations and functions beyond simple mathematical statements. Using multi-sensory activities and games can help make learning this difficult concept more enjoyable.

Let's examine some activities and games for graphing linear inequalities.

Human Inequalities

Engage students in a kinesthetic activity to graph inequalities using their bodies.

Materials

  • Tape
  • Coordinate grid
  • Sheet or table cloth
  • Cards with inequalities written on them

Teacher Directions

Preparation

  • Prior to the activity, create a coordinate grid on your classroom floor using tape. If you have a tiled floor, use the lines on the floor to help.
  • Create cards with linear inequalities written on them.

Activity

  • Show the class an example of a linear inequality. Discuss how to graph the inequality including what type of line to draw based on the inequality symbol and how to shade the graph.
  • Model how to graph some example linear inequalities on a coordinate grid.
  • Divide the class into small groups and provide each group with one of the cards you created.
  • Groups will take turns using the coordinate grid you created on the floor to graph their inequality. Students will represent points on the line.
  • If the inequality is less than or greater than, students will not hold hands to represent a dashed line. If the inequality is less than or equal to or greater than or equal to, students will hold hands to represent a solid line.
  • Provide the groups with a sheet or table cloth. Students will hold it in their hands to show which side of the line would be shaded.
