A reader brought to my attention the fact that the link for my post about free thematic units in Spanish and other languages did not work anymore. After a bit of research, I discovered that the pages were archived. The new link is: http://wayback.archive-it.org/855/20101103145624/http://nflrc.iastate.edu/pubs/units/unitsList.html
I will fix the link on the original post, but since I thought this was such a great resource, I thought it deserved a new post as well. Also, I would highly recommend that you download the material to your computer. I will be doing the same. Thanks again, Molly!
