Regular polygons. In this collaborative activity students find the interior and exterior angle measures of regular polygons, the sums of their interior angles, their names and their number of sides.
Polygons range from 3 sides to 15 sides. All polygons with 13+ sides are named "n-gon" in the answer key (you can have your students use their real names if you'd like). There are 26 pennants in this activity - 2 pennants for each polygon. One one of the pennants for each polygon students name, find the interior angle measure and the sum of interior angles. On the other pennant for each polygon, students name, find the number of sides and the exterior angle measure. Once a pennant is complete, it can be hung along a string in your classroom to show the world that, "Hey, we know our polygons!".
The download includes 26 pennants (2 for each polygon), an optional student answer sheet and an answer key. Each group of students can be given a set of pennants, scissors and either glue, tape or a stapler. Students can be in charge of cutting out the pennants. Groups can compete to see which group can complete the most pennants or your entire class can add pennants to one string as they complete each one. You may also choose to have your students color their pennants to add to your classroom decor.
Choose "Fit" and uncheck the box next to "Choose paper source by PDF page size" if you are having trouble printing. I create the files larger to get more detail and this seems to confuse some printers. These settings should do the trick.
