"My Class Fish Bowl" is a fun behavior management tool. The students work for "bubbles" in the fish bowl to ultimately earn a class fish!
For our class, each time the students receive a "class compliment," I draw a bubble in the bowl. Once they've earned 10, I cross off one part of the collection (the bowl, then the marbles, etc.), bring it in to class, and start over for the next item. The students LOVE it! We usually earn the fish between the 7th and 10th week of school, but you could speed it up or slow it down.
I got this idea from a teacher on my grade level who sells some cute stuff on TPT: Emily Coffey. Look her up!
