My Geometry students agree that "angle location day" is the best day of the year. This activity gets them out of their seats and they have fun learning. The first time I ever did it, years ago, a kid named Robert looked upset and said, "I seriously wish I knew where to find corresponding angles." He learned and had a great time and I have been challenging students every year since with this out-of-their-seats partner activity. There is an expense with the set-up, but it can be used over and over and sometimes math departments have money for activities like this.
