Regular Polygons - Angles and Perimeter Flash Cards Matching Game

Regular polygons are all around us, and their beauty is that they provide so many opportunities for increasing mathematical understanding! With this amazing flash card game, students explore these areas by working together to match 20 sets of 5 cards each. Included are 10 different polygons, and student must match the picture, name, perimeter, and sums of both interior and exterior angles. Each type of polygon has 2 sets, so that students can clearly see that angles remain the same while the perimeter changes. Students quickly learn that the sum of the exterior angles is always the same, and they come to recognize that, as the number of sides increases, the shape approaches that of a circle. This activity takes students away from worksheets as it promotes mental math, and increased comfort with terminology. It is ideal for English language learners, and for practice in mastering the Common Core Standards. Whether you use these cards as a center or whole class project, your students will be engaged as they learn in this kinesthetic activity. - from Judy Seki for "Math in a Flash!"
