Instructional Ideas

• Use the resource to introduce solving inequalities

Classroom Considerations

• Learners need to know how to translate, reflect, and dilate points on a number line
• Note that the lesson only covers two-step inequalities and inequalities with variables on both sides (no distributive property or combining like terms)

Pros

• Includes printable worksheets
• Teacher guide contains answer key to practice problems
• Lesson introduces pupils to a unique perspective on solving inequalities through transformations on a number line

Cons

• Outdated state standards information
