Here's my two cents: I wouldn't count reminders b/c that is not HER behavior, and she truly can't control whether her teacher is feeling rather patient one day and seriously annoyed another day. Though still dependent upon her teacher (and thus, fallible) I would splits dd's day into smaller increments and define one or more goals for her during these times (ie: will raise hand before talking, will stay in seat - etc- for 15 minutes). If she gets one warning /reminder or less, she earns a point/tally mark/coin /you name it. She always gets to start new with each period (and the periods gradually lengthen as she experiences success. The "earning " system is really based on what motivates her (running errands for teacher, lunch with teacher, extra computer time in class, food, trinkets, praise) .
