This lesson teaches how to identify and sort quadrilaterals by examining their attributes. It begins with an introduction to polygons, explaining that they are closed figures with straight sides. The lesson then discusses sorting shapes based on attributes and focuses on identifying quadrilaterals, which are polygons with four sides and four angles. The video examines specific shapes to determine if they are quadrilaterals and concludes with a summary of the key points.
