The poygons powerpoint introduces your students to the definition of a polygon, six polygons, the definition of a vertex, and a slide that shows what's NOT a polygon.
There are posters that match the powerpoint to hang up in your room as a reminder for the students.
There are also two worksheets. One is creating a table that has the students write the polygon, the number of sides, and draw a picture. The second worksheet has pictures of polygons and they have to write which one it is.
