## Reflection: Developing a Conceptual Understanding Simplifying Square Roots - Section 4: Homework

During my journey into the Common Core, I have embraced the power of estimation.  Earlier in my career, I overlooked this value of this mathematical habit.  Here are some of the things that I have come to realize. By estimating the solution prior to solving, students reap a number of benefits.  They build their number sense.  For example, this Student obviously understands square roots as evident in the explanation of their work.  Estimation also enables students to judge the reasonableness of their solutions which is particularly important in modeling real-life problems.  Finally, estimation supports the conceptual development of many mathematical skills fundamental to algebra (Math Practice 1).  To estimate the solution to a radical equation, for example, students need to understand what that root will do to the equation.
