Education is a community affair. Your children have books. Sit down and read some of the lessons with her. It's your job as a mother to encourage her to do what she can and what she will with what's available. Smart kids learn no matter what. I'm not saying the teacher might not be able to do better. I'm saying that you don't get to just sit back and complain. Volunteer in the class room. Homeschool her. Put her in a private school. Tutor her after school. The options are endless.
