I taught low kids too
One of the things said at a workshop I went to for getting reading grant money was to have the children read to the paras in the building. One of the more successful schools had a time in the day where the kids would read to the paras. Well, we had no paras, but we had a secretary, bookkeeper, principal, nurse, alternative room, SPED teachers, and other students in the upper grades, (K-8 school). I went and asked these people if I could send kids to read to them. The principal loved the idea. The kids loved going around the building and reading to others. To them it was showing off their new skills. I don't have numbers, but I know the reading improved because of the practice they had. The self confidence grew too, because these caring adults always let the children know how great they were reading.
It is our nature to want to do well in things and when adults let the children know they are doing well, we work to improve ourselves.
I hope you find something that works for you. In an area where good things don't happen often, it is hard to get things going. Keep at it. I am sure you will get improvement out of the kids.
