At the end of the school year, there are certain conceptual understandings that we want our students to have. Achieving these learning goals lays the groundwork for more sophisticated understandings as students proceed through their learning experiences. The Understanding Evolution Conceptual Framework is an effective tool for identifying a sequence of age-appropriate conceptual understandings (K-16) to guide your teaching. The Framework is divided into five strands, and a selection of teaching resources (i.e., lessons and activities) targeting most concepts has been identified. See the complete conceptual framework for all grade levels.
