This week the second grade students have been working on classifying polygons. Polygons are classified based on the number of sides, angles, and vertices that they have. Below is a list of the different types of polygons that your child has been learning about.
(Note: We have also discussed that a quadrilateral has four sides, but there are some special types of quadrilaterals such as a sqaure, rectagnle, trapezoid, and several others. They do know need to be able to identify each type of quadtilateral at this point. They need to understand that any polygon with four sides is a quadrilateral.)
The video below is one that your child watched about polygons. It shows an example of the differnt types in order for the to see what a regular polygon looks like.
