Open House and Failing Grades

Well, where do I start?? Today was Open house at Christian's school, I know, kinda late for open house, but it was originally scheduled for the day that Hurricane Ivan hit, and then the kids were out of school for 19 days. So, finally it was held tonight.
I got Christian's report Card...he has a F...Yes, an F in reading. I can't believe it, I knew he was below grade level, but I didn't know he was doing that bad. Here are the rest of his grades:

MATH: 74/C
READING: 55/F
LANGUAGE: 71/C
WRITING: 70/C
SPELLING: 79/C
SCIENCE/HEALTH: 95/A
SOCIAL STUDIES: 94/A

HANDWRITING: SATISFACTORY
MUSIC: EXCELLENT
ART: EXCELLENT
PHYS ED: EXCELLENT
CONDUCT: EXCELLENT


IN THE NOTES SECTION, IT SAYS HE DOESN'T TURN IN ALL HIS WORK AND COMMENTS DIRECTLY FROM THE TEACHER ON THE BACK SAY: Christian's having a hard time staying organized with his work. He loses a lot of it. Keep reading and studying multiplication facts

Hmmmmm...so what does a mother do? I thought he was doing better than that. His teacher told me he was in a group to help with reading, but the group was too big, so he was removed because there were kids doing worse...worse than and F???!!! Is there a way to help and ADHD Child with staying organized. He is currently in speech and doing satisfactory says the teacher. I just don't know what to do. I have taken away his play station, next will be his TV. But am I being too hard? Are his problems health related (ADHD?). Maybe I am just rambling. Any advice and suggestions would be greatly appreciated.
