An easy to use interactive game to play with any class after introducing corresponding angles, alternate interior angles, same-side interior angles, alternate exterior angles, and same-side exterior angles. A great way to review material. No materials or set up necessary. Students hold up the set numbers of fingers as instructed to match the correct angle pair shown. Easy for the teacher to quickly assess the understanding for every student in the class. Answers are listed on the last slide with the number of fingers students should be holding up and the correct angle pair name. The teacher may want to printout the last slide before beginning game for better recognition of the students answers.
