Through the great folks in the Google Certified Teachers community I’ve learned that you can now sort your search results by readability. The readability index is a bit coarse, but it is helpful none-the-less. The index use a simple ranking of “basic,” “intermediate,” and “advanced.” In order to sort by readability you have to open the advanced search tools then select “reading level” from the drop-down menus. See my screen captures below.

Refining search results by readability could be helpful when you’re looking for online reference materials to match your students’ abilities. Likewise, this could be a good feature to show to students so that they can find materials appropriately matched to their reading abilities.
