Students find areas of irregular shapes by counting unit squares in this collaborative activity that doubles as class decor. Once a pennant is complete, it can be hung along a string in your classroom to show the world that, "Hey, we know area!"
There are 2 sets of pennants (30 pennants each) in this download. You can see examples of both in the thumbnails. One set asks students to find areas of irregular shapes by counting unit squares. The other set asks students to find the areas of the same shapes and also the shapes' perimeters. A good extension activity to this set would be to ask students about the relationship between area and perimeter and if shapes with the same areas will always have the same perimeter.
Included are 30 pennants that each ask students to find the area of an irregular shape by counting unit squares and 30 that also ask students to find the perimeters of these same shapes. Also included are optional student answer sheets and answer keys. 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.
