Count each loop, except for the beginning slip knot and the loop that's on your hook (shown below).

Single Crochet
To count short stitches like single crochet, look at the top loops (shown below).

Double Crochet
To count taller stitches like double crochet, look at the upright "stems" along the side of the row that faces you (shown below).
