This first set of flip-books, showing some transformations of the graph of a line, have been keeping me occupied. I have a small circle of math-friends to send these to, for comments, but I would like to expand this circle. It has taken me by surprise how many revisions this book has gone through already.
There’s been revisions in sequence, color, line weight and paper weight. It feels like this tweaking can go on endlessly. First, though, I would like to get this in the hands of some more teachers who are willing to put a copy of this flip book into student’s hands, and then tell me how it goes. I am aiming at something like a template to use as base for his book as well other books like it.
Is there anyone that I can interest in playing with me and my books? If you teach the equation of a line, and would like to have one of these books in exchange for giving me some feedback and suggestions, please let me know. The contents of what’s in the book is similar to the GIF in my last post. As I said there, the GIF can show the concept, but it seems to me that it ‘s more valuable if students hold the book in their hands, as this then allows them to slow the animation down, so that they can work out for themselves the secret of what’s going on between the equation and the picture.
So who wants to play? Leave a comment below, or send an email to me in the address that’s listed under my About tab. Later this week I am hoping that three teachers will receive a little book in a gold envelope.
