Wow D.-
I'm a Mom of 4 college students with night and day personalities, and believe me your 7 year old is quite healthy, full of joy and very bright. Of course she has to learn to use her gifted personality/intellect properly.
My second oldest (daughter) was similar . She had/has major leadership qualities that her teacher noticed and work on cultivating.
There were times she'd put my daughter in charge of teaching (at the black board) part of the class while she worked with another group (Montessori school/ 2-4th graders. Derri was in the 3rd grade level with advanced reading abilities)
However, if a student said the wrong answer, Derri would yell out the right answer to the student. This of course would annoy the teacher and she would have Derri sit down.
Yet, the teacher understood her personality and would eventually allow Derri to try it again another day. (info from parent/teacher meetings)
And yes, Derri operated this way at home, too, so I throughly understood the happenings in the class room.
Using "good judgement" on "when" and "how" was a lesson we began to see Derri needed and really giving her understanding on "consequences"
Ideas--
Sit in her classroom (Surprise her. If possible, don't let her know when you're coming) so you can see first hand her excitable outburst and those times when she may be sidetracked into neighborly conversations. Stay and have lunch with her in the cafeteria. Bring her a special treat with you (cheese stick, pickle, a small piece of her favorite healthy snack) ~Keeping the visit special.
Be honest with her. Let her know you'll be coming now and then just to observe her in class room settings, so you guys can have better role play at home that will help her control her actions better.
PLUS you really enjoy this special time with her.
Take turns with the Dad's in doing this if possible.
Give her the vision to aim for the reward that come when a student gets "green" for a certain time span. This is not bribery, but helping to build understanding of good consequences and bad consequences for a young heart and mind.
Remember to role play real-life school situations at home.
Allow your daughter to paste a big green light on her book-bag or stick it inside where she can be reminded.
Posted (in her room, the kitchen, family room)- a light with numbers (1 through ??)
Let your daughter record her accomplishment or non-accomplishment of the day.
At the end of the established time period---more green over yellow you can receive a pretty satisfying reward...but a red in the mix can take down the power of the green.
All green can really "make you happy"!
We found that letting Derri choose the consequence she'd like to receive was really helpful.
I do appreciate the fact the the teacher is not majorly concerned---usually they possess a gift of interpreting actions of their classroom children's personalities after spending much time with them. (and years with various types)
I hope some of this is helpful to you and your family.
I love your heart. You are a beautiful Mommy~
Much success.
