While she is working on her homework, what do you observe?
Does she understand the instructions?
Is she easily distracted?
Distracted by the TV, by your phone calls,by outside sounds, by the pets?
Does she seem to keep getting up and doing other things?
Getting a snack, sharpening the pencil. going to the bathroom.
How does she do if you sit in the same room as her?
How does she do if you sit with her?
Does she talk nonstop while working on the homework?
IF you work with her, how much does she need you to show her the task? If it is math, do you have to sit for each problem?
When she completes a problem, do you need to show her the next problem?
I used to tutor at our daughters school.
There were many children that did well standing up to do their work..
Or the bouncing balls that they could sit on while doing their work helped.
Other children did better if the homework was broken down into smaller parts.
We would cut the homework into sections (ask the teacher for 2 copies of hand outs.)
Or we would use a "guide" to only show 1 problem at a time in the book.
We would use a guide to allow their eyes to follow the text on the page.
When you pick her up from school, what is the schedule of what happens when you get home?
Snack?
Downtime or directly to homework?
Outside play or TV?
Each child can be different.
Our daughter was starving when she got off from school. She would have snack.. and then down time doing whatever she wanted. TV, Nap, Play outside, or read.. Then she would get her homework started. She did best if the TV was on..
She did not need me to be in the room with her, but some of her classmates, did best if their parents were close by.
FYI, in High school, she had her TV going, would be on the computer and talking on the phone!!! All while working on her homework.. She says even through out college she could still do this.
But some children cannot have any distractions at all.
I would study your daughter or ask her teacher what she is observing.
