I do a set of jumping jacks, a set of dragons, then a plank. I do it four times, until I've completed all my plank variations, and then I get to the other stuff.

I do all sets of my weights in a row, and not split up into circuits. I tend to mix my leg raises with my crunches, though.

I've tried adding pull-ups, but after doing any of the training in here, I seem to be too tired to do even one properly. I can only seem to do them when I'm nice and rested, so I tend to leave them for my chin-up bar at home when I'm puttering around the house.
