I wrote a 9 lesson photography unit for my children in January. I've posted it on my Wordpress blog because Google will allow me to insert images, but not pdf files. If you'd like to have a copy, you can it find it here:
I wanted to make it available for free on teacherspayteachers.com, but there is a charge for every download. On Wordpress, people can view the file and print it without having to download it.
If you take a look at it or use it, let me know what you think!
As I have other resources that I've written, I plan to post them on that page.
