Public School Woes

Impressed? I am writing again all ready and it has not been months.
Anyway....
I am frustrated with the school system and am wishing now that I just had gone ahead and home schooled. If only I could afford the university model school in Sugarland. Rebecca got an N for a daily grade in gym today. I realize it is just gym but still. Why did she get an N? Was it because she did not participate? Nope, it was because while trying to run a half mile in 10 minutes she fell and scraped up her knee and went back to the start to show her teacher and thus started from the beginning again only the time did not restart so she only technically completed three laps in 10 minutes so they gave her a N and sent home a prey harsh letter saying how she could not complete something that was so easy. Talk about a self esteem buster. To top it off apparently they have a book where if you misbehave and they speak to you twice the third time you have to sign this book. I guess acknowledging you misbehaved or something. Well, because she was unable to finish her 4 laps they made her sign the book. S, not only was she given a N a if she did not do what she was supposed to but she was also lumped with the "bad" kids. I am not a happy mom right now and am still trying to figure out ow to approach this.
Then I am having issues getting her ready for school in the morning. She cries that she does not want to go to school, she does not like school, etc. I have had to threaten to leave with her still in jammies, physically chase her after she has ran back in the house, and physically get her out of the car once at school. It is getting worse. I think she is bored at school. They learn a new letter each week (something she already knows) but also for each letter they do the same exact worksheets. So essentially she is doing the same work every week. Even I am sick of looking at it. The teacher has said I could send work in that I want her to do. But I guess I do not feel like it is my responsibility to do this. Plus I do not want Rebecca to resent me. I think the work should come from her teacher. If I am going to send the work in I mine as well just home school her. I do love her teacher but I guess I just want her more challenged. And it does not help that I am so non-confrontational. This is so hard for me.
