This Instructional Activity is a part of the Lesson 13, Unit 8, Grade 8. The purpose of this activity is for students to use rational approximations of irrational numbers to place both rational and irrational numbers on a number line, and to reinforce the definition of a cube root as a solution to the equation of the form x^3=a. This is also the first time that students have thought about negative cube roots.
