Find out what Eddie is interested in - and give him a few books in English on that topic. If, say, he's interested in mechanical things, get him a copy of "How Things Work" - https://www.amazon.com/How-Things-Work-2nd-Illustrated/dp/078583740X/ref=asc_df_078583740X Perhaps a Whole Earth Catalog, if you can find one - and a dictionary, English only. He'll pick up English on his own with a bit of effort once he has a good reason to do so.
