This number sense lesson focuses on simplifying radical expressions. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students read the radical expression and identify the radicand. Then, they find the prime factors of the radical expression and rewrite it as the product of prime factors of the radicand. Finally, they simplify the radical expression and interpret the solution. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
