General Lesson Information
 Lesson Plan ID: 35592 Title: Square and Cube Root Salad Overview/Annotation: This lesson will develop the knowledge of squared and cubed numbers. The students will know when to use the square root and cube root to solve an equation. The students will memorize perfect squares and some cube roots. The answers will be left in radical form. Finally, the students will be able to identify the radicals as rational or irrational.This lesson results from the ALEX Resource Gap Project.
