With most girls you have to be brave and take a pleasant, complying child and put them into a 'at least somewhat' challenging academic situation. I don't know if it is biology or culture, but at this moment in time, girls tend to 'make the best of things' to a point way beyond what is safe. Kids rely on us to know what is right for them and to do it, so if you don't skip her, you are sending her a powerful message about your values, that she will likely internalize.
Grinity, you nailed it here... and not to mention that girls will learn to accept this the rest of their lives, causing all sorts of issues, especially mental/emotional ones! I am living proof of that, and I know several other moms around here have similar stories that can be traced back to being bored in grade school...
