Instructional Ideas

• Use the resource as an exploratory activity to introduce solving linear equations

Classroom Considerations

• Lesson requires Internet access if using balance scale applets
• Note that while the lesson indicates alignment to Algebra I, it would be more appropriate for middle school under the Common Core standards

Pros

• Teacher guide contains links to websites for solving equations using balances
• Includes printable worksheet/note taking guide

Cons

• Contains outdated standards information
