This is a perfect tab foldable to glue in any interactive math journal. It provides definitions, theorems, a corollary, and three examples for each. I have attached directions on how to put the foldable together.
To use this in your classroom, simply print out one copy of page 3 for each student and guide them through the directions. Then use the answer key provided to teach a wonderful lesson on the polygon angle sum theorem and its corollary.
