Reflection: Checks for Understanding Simplifying Square Roots - Section 1: Warm up and Homework Review


Square roots are something that Algebra 2 students have already studied for several years.  My goal for this lesson is to ensure that their knowledge level is deep enough to apply to quadratic and then polynomial equations.  This warm up lets me know how many students understand the basic principal behind square roots.  I did have several students just use a calculator and fess up to that.  This student (1), while missing the concept, used some reasoning by associating the decimals.  This student (2) gave me the answer that I was looking for, namely he used the nearest perfect square to estimate the solution.  Given the number of students who made mistakes on their warm up, I am glad we did this lesson.
