I don't know, Have you talked to her about it. 9 year olds are alot smarter than they look. One way to gauge whether or not taking things away is working is if you keep doing it and she just stops caring about the things you take away. If it turns out that its a challenge she's looking for which is likely, then you could find a way to make it more challenging. for instance if her assignment is to do 10 addition problems you could tell her to then divide all her answers by 2 and then add 3 on a seperate sheet of paper or i dunno use word problems to make the questions and answers relevant to her. If kelly goes to dance class and sees 8 dancers on the floor fully dressed how many pairs of toe shoes or split sole jazz dance shoes does she see?
