This Instructional Activity is a part of the Lesson 5, Unit 8, Grade 8. The purpose of this activity is for students to think about square roots in relation to the two whole number values they are closest to. Students are encouraged to use numerical approaches, especially the fact that square root of a is a solution to the equation x^2=a, rather than less efficient geometric methods (which may not even work). Students can draw a number line if that helps them reason about the magnitude of the given square roots, but this is not required. However the reason, students must construct a viable argument.
