Where did all these variables come from, anyway? The previous lessons in the series ask learners to solve multi-step equations using the distributive property, combining like terms, and using inverse operations. Now scholars solve equations with variables on both sides of the equation.

Instructional Ideas

• Use the lesson as an independent learning challenge; allow individuals to choose to watch the video or read the printed lesson

Classroom Considerations

• Requires Internet access to utilize the video resource
• Equations still require strategies learned in previous lessons
• Review of solving equations with variables on a single side may be necessary before introducing variables on both sides

Pros

• Video provides clear explanations of the methods used when solving equations

Cons

• Video does not include examples of problem solving
• Practice problems become complex quickly
