I had the same situation with one of my sons. Long (very long) story short, he was diagnosed with ADHD. You may want to talk to your pediatrician about her behavior. It may just be a learning thing for her - she has to mature a bit to gain the self control, or it may be something like ADD/ADHD which means she is not fully in control of her actions. I strongly recommend you speak to your pediatrician about this so even if she is not diagnosed, then at least you'll know for sure what it is not. BUT, if it is, there are several avenues to explore (medication, behavior therapy, diet, etc). If it is ADHD, then the earlier you catch it, the easier it is to deal with and the less hassles you, your family, your daughter, her classmates, her teacher have to handle. I spent 9 months of constant stress and research and waiting on doc appts, and doubt and concern that I hadn't been a good enough mother, etc - you name it, we went through it emotionally. My son no longer has uncontrolled outbursts, he no longer fights the teacher, he is more flexible (although not 100% but much more so than he used to be). I was afraid he was going to fail first grade he was so uncooperative. But when he wasn't uncontrolled, he was a sweet, inquisitive, friendly boy who the teachers just adored - a true Jackyl and Hyde kinda kid. It was that extreme in personality that lead us to put him in therapy which lead to his diagnosis. I am grateful to the docs we've seen - the majority have been just so caring and concerned and helped us tremendously.
While we were dealing with all this, we too tried a variety of reward charts etc, here's what we found:
1- they don't care about sticker charts.
2- for a child having trouble controlling himself, the idea of waiting a week for a reward was just too much to process.
3- we tried using marbles in a mason jar. We did this all day, everyday for every good thing the child did from doing his homework without complaint to trying even a single bite of a new food. If he did something without being asked - like helping his brother, he got 2 marbles. This one worked very very well. Since it was immediate results for his actions all day, it seemed to work better. They got to put the marbles in their jars. We marked the jar in 4 sections. As they filled the jars to each mark, they got a reward of some sort. Once they filled the jar, they got to choose from much larger rewards. By then, they were much more into filling it up. His 1st grade teacher (last school year) did a similar thing with little interlocking plastic rings. When he did good, he got a ring to add to his chain and if he got X, then he'd get Y as a reward. She worked hard with us to help.
We did the marble jars for almost a year and after 8 or so months, we did kind of stop giving the marbles out since by then the behavior was better. After a few months of no real reward system, we've recently moved to a new one. I found this foam/paper tree at the craft store, we put it up on the wall upstairs between the bedrooms. I cut out a bunch of bird shapes and leaves and when the boys do something good (again, try a new food, show good manners for the day, help with the dishes, etc) they get a leaf/bird. We write their name on it and the date and what the leaf/bird is for- "I showed good manners all day". I don't think this would have worked as well a year ago, as with this, the reward is the leaf/bird and the sense of pride vs the marbles were really bribes for good behavior with definitive rewards (movie night, pick a game, choose dinner, etc).
Sorry this is so long and rambling, but I hope you and your family find strength in God and accept the gift of doctors to help with your daughter.
