Upper Crunches Lay on your back, lift your shoulders off the ground and crunch your abs (There are too many variations to list, some of my favorite are with legs perpendicular to my body, and on a decline bench.)
Lower Leg-Lifts Lay on your back, lift your legs up until they are perpendicular to your body, lower back to a couple of inches above the ground, repeat
Knee-Ups Support your body off of the ground by either holding on to a bar, using arm slings, or a leg lift chair, lift knees up to chest and back down while focusing on your abs
Situps Lay on your back, lift your legs up until they are perpendicular to your body, lower back to a couple of inches above the ground, repeat (You can do these on a flat surface, on a decline bench, etc.)
Obliques Trunk Twists Grab a bar (a broomstick or light barbell works great), rest it on your traps behind your head, bend the knees slightly, lean forward, and twist your body to the left and then to the right
Side Crunches Lay on your side and crunch to your side
Bobbing and Weaving Move to the upper body to the left, to the right, to the front, and to the back.  Practically, you can do martial arts or box at the same time so you don't look too ridiculous
