Recess Pets - fixing outdoor behaviour problems

We were having some issue in our kinder room at recess time. They were being very hands on and strugging to remember how to walk in a line. Too many sillies! So I came up with these "Recess Pets". They were just clothespegs with pompoms glued on and googly eyes:

The children were introduced to these pets one day and given a very important task. Their job was to care for these pets. They only came out at recess time and they cared for them by making good choices. Helping friends, using words etc. They lost their pets by being hands on, not coming when the bell goes, making poor choices etc. The children then got to choose a pet and we wrote their name on the back of them. At first recess the pets were clipped to their coats and out we went. If their were any problems outside, the children got a warning first and then their pet was removed. Back inside, the children who kept their pets safe were given a green box for the recess:

Everytime their pet came in safe, they got another day coloured in. Once the children had 5 squares coloured in they got a prize. At the end of the day all of the pets were returned to the leash for the night.

Prizes didn't cost us anything either. We had this book called "Treasure chest" it was just a small scrapbook album I had at home:

 Inside, I cut 8X8 paper down to the books size and taped in little prize cards:

Here is the list of prizes we used:
Bring a stuffed toy to school
Get first choice of outdoor toy
Show and Tell
Have a good note sent home
Read a book to the class
Play a game with the teacher
Use special stickers in the art centre (very popular with the girls)
Sit in a special chair at the carpet
Be in charge of sweeping floors (believe it or not but there was constant arguing over sweeping and washing tables at lunch time)
Be in charge of washing tables
Switch spots at lunch
Get a drink from the water fountain whenever you want (the child got a badge to wear as their "pass")
Carpet captain for the day
Line leader for the day (Both carpet captain and line leader prizes included a badge that they wore to state that they were carpet captain (make sure the children are quiet and criss-cross) and line leader (first in line all the time))
Use playdough at freetime
Sit beside a friend at lunch
Have lunch at the teachers desk (This was the MOST popular prize!!! They LOVED this one)
Have a turn in the rocking chair
Computer turn

Introducing the pet routine
When we started the recess pets, the pets were given out every recess and collected every recess. Once they got used to the pet routine, we gave them out at first recess and collected them at the end of the day.

Things I would do differently
I would add pictures to the prize book so it would be more independent for them to choose. They are still learning to read so they needed some help reading all the prizes.
