This is a great partner activity that should be used after introducing the concept of corresponding, alternate interior, alternate exterior and consecutive interior angles. It includes two pictures for practice. Students take turns, or "ping-pong" back and forth recording the angle they are to identify in each round of play. For example, Round 1 they are to identify all pairs of corresponding angles without duplicating their partners answers.
Dry Erase pockets are a great tool in this activity if you have them available as students can isolate the lines and the transversal they are using, erase and move on to the next set of lines.
I have included some helpful hints to remember as you use this activity in your classroom. I use this first as just a recognition tool and then later as we move into parallel lines and congruent relationships.
