Kindergarten – Unit 5: Identify and Describe Two-Dimensional Shapes
In this unit your child will work to build an understanding of the following:
Attributes of a Polygon.
Distinguish between Polygons and shapes that are not polygons.
Count the sides and vertices of a polygon.
Identify and describe: triangles, quadrilaterals, trapezoids, pentagons, hexagons and octagons.
Combine shapes to make a new shape.
Create polygons using a variety of tools.
Identify shapes in the real world.
Counting Sides and Vertices to
Your child can number the sides and vertices to help
them determine the name of the polygon.
Triangle: Polygon with 3 sides, 3 vertices
Quadrilateral: Polygon with 4 sides, 4 vertices
Pentagon: Polygon with 5 sides, 5 vertices
Hexagon: Polygon with 6 sides, 6 vertices
Octagon: Polygon with 8 sides, 8 vertices
Helpful Links for Unit 5:
Polygons are plane shapes made up of line segments that
connect at the vertices’.
Sample tasks your child should be able to work through by
the end of the unit:
Identify shapes that are polygons and shapes that are
Count the number of sides and vertices on a polygon.
Name polygons based on number of sides and vertices.
Combine shapes to make a new shape and then name
the new shape based on sides and vertices.

Purposeful Practice at Home:
Use toothpicks, cotton swabs, pretzel sticks etc. to make a variety of polygons. Give clues such as “This polygon has 3
sides and 3 vertices.” Your child will then create the polygon with their materials and name the shape.
Take your child on a Polygon scavenger hunt. Identify different polygons in real life. Rectangles (cabinet doors, wood
planks on the floor), squares (tiles on the floor), octagons (stop signs) etc.
Practice drawing polygons, number the sides and vertices and have your child describe shape based on the number of
sides and vertices.
