1.6A Audience: First Grade. Behavior: Classify 2-dimensional shapes using informal geometric language. Condition: Ancho Chart. I would introduce some familiar 2D shapes and ask the students to identify how many sides and vertices using an anchor chart.
This worksheet was designed to assess identifying polygons. It includes 8 different polygons and places to label the shapes name, number of sides and number of vertices it has. This may also be used as a quick math journal entry. The answer document is included.
