Wrap and turn...
Knit to the turning point. Slip the next stitch, bring the yarn to the front (as if switching to purl), slip the stitch back to the left needle, then bring the yarn back to the back. This is the wrap (see hoe the yarn is wrapped around that stitch you slipped?).
Then, turn - just like you would at the end of a row.
A purl wrap is almost the same, except you slip, bring the yarn to the back, slip, and bring the yarn back to the front.
