I agree with blondie I would make a checklist go over it with her teacher and bring it to your child's Dr. and I would do it BEFORE 1st grade starts the longer it takes to figure out the harder it will be. I think that she may be board because it's too easy for her or she has no interest in the subject. If there's no interest or I guess; either way find a fun way to review homework. When she reads a book make her pretend that she's the character by using what they would sound like. You'll find her laughing! Good luck!
try to visit this site, http://besthealthoptions.com/baby-child-care it has great articles about child behavior, i'd learned a lot from it. gud day!
I know that must be frustrating but it does sound like it could possibly be ADHD (which is now the term supposedly even if they DON'T have the hyperness to it) - It could be a number of other things as well - Is she bored in school - Is the stuff coming to easily for her - Even a thyroid disorder can mimic ADHD symptoms (I was just at a seminar a couple months ago about this) - My suggestion is to talk with her teacher - He/she should have a checklist that you can go thru - After that take her to her pedi and see what they say - Do it before it is too late - I started out that way in school too and I did HORRIBLE all the way through. Good luck to you.
