Fantasia Mathematica, The Mathematical Magpie, and The Space Child's Mother Goose are collections of short fiction, satire, and miscellania assembled in the same era as A Wrinkle In Time. I enjoyed them when I was about that age. Wikipedia lists the contents of the first two. I see Rudy Rucker's collection Mathenauts is similar, but a bit later.
