Talk:Frieze Marking Exploration
This project is good because it gets students to understand translation length. It gets them looking for mirror symmetry "in between" pairs of more obvious symmetries. And best of all, with #8, students discover glide reflection on their own.
I changed the exploration a bit. If you want the older version (less direction, more independent exploration) then go to history and get the previous version Barta 18:11, 30 August 2009 (CDT)
