Hello and Thank You for using Just Answer. You may want to use a timer and say by the time the timer goes off in # XXXXX minutes, then you may ??? Your daughter may need breaks between assignments to redirect her attention to something more enjoyable. It is getting toward the end of the school year in many areas and numerous children are already in the summer mode. Also, you may need to set up a reward system, Focus on the positive behavior. For every evening that she does her homework without you having to intervene, then she gets a sticker. After 10-20 stickers, you decide the number, she gets a really big treat or a special outing. You can use a calendar for each day. If she has a problem day, she gets nothing. Ignore her meltdowns and move on. Tomorrow is another day. Try this at least until the end of the school year and see what happens.
Hope this helps!!!!
