Possibly when they're a bit older, but possibly now…Check out the NO FEAR SHAKESPEARE series. These are study guides, really aimed at HS and college students, but they do a great thing: they show the original text and, on the facing page, a modern English translation, line by line, so that you can read it (much more easily than the traditional method of footnoting some words). I found that these really helped de-mystify Shakespeare for my kids. They originally (at 5th grade or so) mostly read the modern English and glanced at the "translation," but they progressed quickly to being able to read the original text, understand it, and enjoy it. Shakespeare has really enriched their lives, and it's a wonderful academic skill. My son chose to act in in a Shakespeare play last summer, in part because he wasn't afraid of the language and could study it for meaning and feeling.
