What does a classroom look like when it's aligned with the instructional intent of the Common Core State Standards? If this question is on your mind, the Green Flags/Red Flags documents can be used to help understand what implementing the CCSS with fidelity entails. Equally as important, these documents help you understand what a CCSS-aligned classroom would not look like. Meant to act as a guide and a blueprint for what should be included and what should be discontinued in the classroom, these documents can be used to determine patterns of implementation, provide evidence for conversations around professional growth, and for self-reflection. They are not intended for teacher evaluation.
