##### This Simplifying Radical Fractions video also includes:

Rationalizing denominators of radical fractions is one of those skills that pulls together understanding of many different concepts. By carefully scaffolding from easy to hard examples and explaining each example step-by-step, this video presentation effectively accomplishes this skill mash-up. Each example emphasizes a different aspect of simplifying radical fractions, from multiplying radical insides and outsides to reducing fractions to using the distributive property. Common pitfalls and knowing when the problem is fully simplified are also explicitly covered. A great resource to supplement any rational and radical number unit.

##### Instructional Ideas

• Use for viewing prior to class in a flipped classroom model or post for individual remediation and refreshing after teaching the lesson
• Excellent for differentiating instruction and extending advanced learners when teaching multiplying radicals
##### Classroom Considerations

• Video presentation is YouTube based
• This presentation only covers square roots and single-term denominators, no higher order roots or multiplying by the conjugate
• Weaknesses in prime factorization, multiplying radicals, and reducing fractions will all surface in this lesson, so consider having remediation ready if needed
##### Pros

• Pleasantly voiced and easily understood narration
• Each example created and worked to emphasize a different skill in rationalizing denominators
• Problems start easier and gradually increase in difficulty
• Knowing when simplification is complete is specifically addressed in problems
##### Cons

• No printable notes or slides provided
• No seatwork capstone problems available
