GCF Learn Free’s reading site has been on several “The Best..” lists for its simple reading instruction, which is excellent for English Language Learners and new readers.
They’ve kept that site, and have also added several multilingual features to specifically help ELL’s. You can visit their Learn English site here. They plan on adding many new activities there in the coming months.
I’m adding it to The Best Multilingual & Bilingual Sites For Learning English.
