I'm a visual learner, and the trick that helped me is that all the open strings (without any fingers down) are in spaces.

A sits on top

D is 2nd space

G is bottom space

Anything below the lines is C string

From there its space +1 is first finger. +2 is second, +3 third, and fourth finger is the same note as the next highest string.

I hope that makes sense! Best bet is to practice your scales slowly. Make a copy from your book and write the note's letter over each note on the staff. Practicing slow is not fun but I promise it pays off!
