I like that your behavior plan, and sorry--I don't have an idea for you. But I thought I would post this here in case someone is looking for another ocean theme behavior plan.
My ocean theme behavior chart is called "Don't Flip Your Fish!" It works great for for 1st grade. And it is SIMPLE--that was my main concern with my class last year. Here's how it's set up:
You'll need small library pocket cards (labeled w/ student # or name)
Fish cut outs (with a different color on the back than on the front...I think mine are Carson Dellosa and they fit perfectly in the small size library pocket cards.)
Put the fish in the pockets all on the same side. If a student needs 2 reminders they have to flip their fish to the blue side (or the back side.) If a 3rd reminder is needed, you ask for their fish. You could even add a 4th step somehow...I didn't need to last year. Another title could be "Swimming with Good Behavior."
I wish I had a picture, although I don't think I can post pics yet. I hope that helps!
