Free Solving 2-Step Equations With One Variable Lesson Plan for 7th Grade Students

Topic: Solving 2-step equations with one variable

Objectives & Outcomes

Students will be able to solve 2-step equations with one variable using substitution and elimination.

Materials

Pencils

Paper

Calculator (optional)

Warm-up

Ask students if they have experienced solving equations with one variable before.

Ask them to give an example of an equation with one variable and how they solved it.

Write their examples on the board.

Direct Instruction

Define what an equation is and what it means to solve an equation.

Introduce the concept of a 2-step equation with one variable, and explain that these equations have two steps that need to be solved in order to find the value of the variable.

Introduce the four different methods for solving 2-step equations with one variable: substitution, elimination, addition, and subtraction.

Demonstrate how to use each method to solve a sample equation with one variable.

Have students work through a few additional examples using the different methods.

Guided Practice

Give students a set of equations to solve, and have them work in pairs to solve the equations using the four different methods.

Have students present their solutions to the class, and discuss the different methods they used.

Independent Practice

Have students work on a project-based activity where they use a variety of equations to solve for a variable. For example, they could use equations to find the value of a car's speed given its distance traveled and time elapsed, or the value of a project's cost given its duration and budget.

Have students create a poster or presentation to show their solutions to the equations and how they solved for the variable.

Closure

Review the different methods for solving 2-step equations with one variable.

Have students share their posters or presentations with the class.

Assessment

Observe students during the independent practice to assess their understanding of the material.

Have students complete a brief quiz or worksheet to check their understanding.
