Yes, I know this a bit of a niche list, but since I always teach an ELL History class, and I’ve started using short texts instead of a textbook, I’ve been looking for good and accessible sources.
Here is what I’ve found so far:
Brittanica Kids has all of its articles written in three different levels: Kids, Students, Scholars. There is a cost involved, but a lot of their resources are available for free. For example, I found this article on The Compromise of 1850 that I’ll be using in my ELL U.S. History class.
I’ve recently found that Ducksters is another good source.
Let me know what I’m missing!
