I spent the evening creating a power-point tutorial to use in my presentations at the Open Houses at Flint Hill on October 10th and 18th, and I may use it with my students if we get this new fiber unit together the way I envision it. If I could figure out how to link to it, I'd provide a link. Any advice, friends? Or do I have to upload it one frame at a time? I guess you could let me know your email address, and I could send you the file, in a pinch...but there has to be a way to attach it to the blog, right?
