There is a truly wonderful children's book about Erdos, "The Boy Who Loved Math: The Improbable Life of Paul Erdos" by Deborah Heiligman and LeUyen Pham: https://www.amazon.com/Boy-Who-Loved-Math-Improbable/dp/1596...

I think this book really shines in showing why it makes sense to accept "strange" people (or, that other kid in your kindergarten who seems "strange"). Fills me with warmth every time I happen to page it through.
