Lesson Plan: One-step Inequalities: Addition or Subtraction Mathematics • 6th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to write and solve one-step linear inequalities by addition or subtraction.

Objectives

Students will be able to

  • deduce that if the same number is added to or subtracted from each side of an inequality, the inequality remains true, which is the addition and subtraction properties of inequalities,
  • deduce that if the same number is added to or subtracted from each side of an inequality, the direction of the inequality does not change,
  • know that solving one-step inequalities means finding the unknown value to make the statement true,
  • use these rules to solve one-step inequalities.

Prerequisites

Students should already be familiar with

  • the properties of operations in and ,
  • the meaning of variable and constant.

Exclusions

Students will not cover

  • inequalities with more than one unknown,
  • solving inequalities of the second or third degree.
