This Instructional Activity is a part of the Lesson 2, Unit 8, Grade 8. The purpose of this activity is for students to estimate the side length of a square via a geometric construction that relates the side length of the square to a point on the number line, and verify their estimate using techniques from the previous lesson. Once students connect the side length to a point on the number line, they learn that this number has a name and a special notation to denote it: square root and the square root symbol.
