## Reflection: Connection to Prior Knowledge Using Strategies in Working Backwards to Solve Multi-Step Word Problems - Section 3: Practice and Closure

This lesson is conceptually very hard for most students in the beginning. I could tell they were all dumfounded at first  because  they were guessing and shouting out numbers for answers. They want to be right without much thought. They don't think about the fact that there is an equation behind solutions yet. The transition to CCSS is difficult for many students, but worth every ounce of effort to get kids to think about why we are doing what we are doing in math. This lesson is a lot about how...but clearly shows students how the inverse ( or the why) is used to solve the unknown and why the equation works in every instance.
