Solutions to Equations with Variables on Both Sides by ECSDM
Intermediate, Commencement, 8th Grade, 9th Grade
Through the use of Microsoft PowerPoint, a worksheet and an interactive math lab practice site, the topic of solving one variable equations will be introduced. The focus of this lesson is on solving equations with variables on both sides of the equal sign.
This should be used after students have already learned how to solve linear equations with one-step or multi-steps with variables on one side.
Algebra Lab - One Variable Equations
Students will be able to solve linear equations with variables on both sides of the equal sign.
Two class periods - 45 minutes each

Day 1 - Students will be learning how to solve linear equations with one variable on both sides of the equal sign.
Display PowerPoint lesson.
- Follow through each slide and examples.
- Students will first complete a "Do-Now" review of solving linear equations with a variable on one side of the equal sign.
- Then students will be introduced to the steps of solving an equation when a variable is on both sides of the equal sign.
- The teacher will complete the first two examples on the 1st slide to show students how to complete the problems.
- On the next slide, have students practice the four examples.
- Have students go up to SMART Board to share their answers.
- The last slide contains examples with fractions. Complete these problems with the help of the students.
- Class work - Have students start working on worksheet and finish for home work.
Day 2 - After reviewing homework assignment, students will continue to practice solving linear equations using the algebra lab website.
- Either do this as a whole class practice or in a computer lab.
- Print out problems and have students work on them first, when they are done they can enter their answers in the computer to check their work.
Student understanding will be assessed using the Variables on Both Sides worksheet. This worksheet and answer key are available in the Materials section.
