Something like the following might work:

(eval-after-load "ispell"
  '(let ((list (car ispell-tex-skip-alists)))
     (add-to-list 'list '("\\$" . "\\$"))
     (setcar ispell-tex-skip-alists list)))

But I expect it to be very fragile because it might get confused with
escaped or unbalanced dollar signs.  It would be better if this were
supported programmatically (e.g. with `texmathp') in Ispell.  Flyspell
does it like this.  Perhaps somebody interested in this feature could
propose this to the Ispell maintainer.
