My oldest daughter is 11 and in 5th grade. She rushes through her work all the time and then can't remember what she learned. She acts like she doesn't care at all.
I have tried to talk to her, help her with her homework, punish her for bad grades and nothing seems to work. She just got an ipod for Christmas and it's been taken away more then she's had it. Taking TV privileges away hasn't work b/c I have 3 other kids and one TV, so they get punished too then everyone is miserable. She's also not been allowed to go over friends or have anyone over for a week or two.
NOthing seems to work and I can't seem to get her to understand that next year in Middle School it's going to be A LOT harder and a lot more work.
