I agree with the deadlift suggestion, another one is leg curls using the dumbbells. I don't like doing leg curls on a machine, they never fit right and that will hurt your knees, but with small dumbbells they are fine.

Lie on a bench (or floor), face down, with your knees hanging over the edge. Have someone place a small dumbbell between your feet (you will need shoes). Curl up and down, make sure you don't hyperextend your legs.
