Talk:Frieze Marking Exploration

I'm about to teach this, and I use it to introduce frieze patterns, so I don't want to lead them into glide reflection - as you wrote, they discover that on their own. Probably we can come to some intermediate form that works for both of us, but I'm out of time so I'm more or less reverting it. Talk later. Bryan 12:58, 30 August 2010 (CDT)

More direction is fine. I didn't like the question about "Identify the Frieze Group", because they aren't supposed to know the frieze groups yet for this project. At least, my students don't. I'd rather leave it out, and if you want them to do extra, maybe tell them in class (or add it back as an 'extra' sort of question). Bryan 12:50, 30 August 2010 (CDT)

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)
