Inequalities

$0.00

The lesson begins by defining an inequality and reminds students that they solve inequalities just like equations.  Then the lesson discusses the two ways inequalities are different from equations.  First, they use different symbols and second, solving an inequality means finding all of its solutions.  New symbols are introduced in the lesson.  Graphing inequalities is also covered in the lesson.

Inequalities Lesson Plan Includes:

  • Full Teacher Guidelines with Creative Teaching Ideas
  • Instructional Content Pages about Inequalities
  • Hands-on homework activities giving students practice learning Inequalities
  • Answer Keys
  • Common Core State Standards
  • Many Additional Links and Resources
  • Built for Grades 5-6 but can be adapted for other grade levels.

Description

The lesson begins by defining an inequality and reminds students that they solve inequalities just like equations.  Then the lesson discusses the two ways inequalities are different from equations.  First, they use different symbols and second, solving an inequality means finding all of its solutions.  New symbols are introduced in the lesson.  Graphing inequalities is also covered in the lesson.

Classroom Procedure:

  1. Begin by explaining to students that there are some types of equations that when we solve them they have more than one possible answer.
  2. While reading the content pages, reinforce vocabulary and symbols. Give students additional examples of inequality problems in order to help them practice.  Use the additional resources to enhance understanding.
  3. Introduce the notes on inequalities. Have students practice problems with and without graphs.  Use the additional resources to enhance understanding.
  4. Have students practice problems and check to make sure they are using the correct symbols and shading their graphs the correct direction.
  5. Follow Activity page with students. Have them work individually.  Students should cut out the squares and place one rectangle from each section with its matching words, sign, graph, and inequality in a row or column on another paper.
  6. Distribute Practice page. Check and review the students’ responses.
  7. Distribute the Homework page. Help students by doing the first problem so that they understand how to complete the page.
  8. In closing, ask students to mimic the greater than and less than signs with their hands and ask them what an open and closed circle represent.
  9. Allow for responses and discussion.
