Making and Sorting 2D Shapes with Geoboards

Today students made various polygons using geoboards then sketched and sorted their 2D shapes.

Learning Goal: We are learning to identify and describe various polygons and sort and classify them by their geometric properties (sides, vertices).

Success Criteria to meet my goal:
-I have thought about what a polygon is.
-I can identify the polygon (e.g. triangles, quadrilaterals, pentagons, hexagons, heptagons, octagons).
-I can sort the polygons by the number of sides.
-I can sort the polygons by the number of vertices.
-I can draw a polygon (using a geoboard).
