I am in the process of putting together my children's curriculum lists for the fall. I went to the post I wrote about reading comprehension units. When I clicked on a few links for the leaping into 5th grade website, I discovered that the author has taken them down. If I were a betting person (which I'm not), the author has probably taken down her units and placed them on a site like Teachers Pay Teachers and is likely selling them for a fee now. I realize that many teachers have done this.
But, this is the reason that when I put together my reading comprehension plan, I printed off the units I wanted for the future. When you find something on the web, there's no guarantee it is still going to be there tomorrow!
