In this super secret number puzzle, students work with regular polygons. Students need to know how to find the total number of degrees in in the interior and exterior of polygons and how to find the number of diagonals in a polygon. Students need to be familiar with the names of polygons up to 10 sides.
Students find the answers to each of the ten questions and then add their answers together – this is the super secret number. After a bit of time, I tell them what the super secret number should be. If their super secret number matches mine, they probably did their problems correctly.
As an alternative, I have also included a page with a QR Code. This QR Code leads to the super secret number. To add excitement, students can scan the QR Code instead of just having the teacher tell the class the Super Secret Number.
An answer key is included.
