Willfull 6 year old boy, on my last straw

Just wondering... What does your school do for children who are misbehaving? Our school has them 'flip their color card. Neither my 6 or 4 year olds care about doing that. My 6 year old will flip it regularly once, but only from time to time twice b/c he has to miss some recess and go to bed 30 minutes early. My 4 yo laughs at flipping his card until they starting putting him in time-out. He wouldn't even sit in time-outs for them until I stepped in and started sending him straight to bed when he comes home with a note about refusing time out. Don't want to start an uproar, but sometimes I really do wish the school could still give children a (reasonable) paddling! That would certainly stop my oldest in his tracks! Would never do that to my youngest b/c would bring up past issues.
