Lesson Plan: Two-Step Equations
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to form and solve linear equations in two steps using addition or subtraction and multiplication or division and apply this knowledge to solve problems in context.
Objectives
Students will be able to
- understand that solving a two-step equation means finding the unknown value to make the statement true,
- solve a two-step equation by adding or subtracting a constant and then multiplying or dividing by a constant,
- solve word problems by forming and solving a two-step equation,
- solve problems in a geometric context by forming and solving a two-step equation.
Prerequisites
Students should already be familiar with
- forming and solving one-step equations,
- adding, subtracting, multiplying, and dividing positive and negative integers.
Exclusions
Students will not cover
- equations involving brackets,
- equations involving more than one variable,
- equations that require more than two steps in their solution,
- equations where the unknown appears on both sides.
