Have you been told that you need to start using a claim, evidence, and reasoning (or C-E-R) framework for writing in your classroom? Maybe you need to closely adhere to the Common Core State Standards but aren’t quite sure where to begin. If you’re like me, you may have been told by administration-on-high that the whole school would be using C-E-R language in their classes to build consistency and teacher equity for students. Regardless, here you are wondering, what the heck is claim, evidence, and reasoning anyway? In this post, I aim to break it down for you.
