My child has not been completing his assignments so his teacher emails me to let me know. I offer to support her at home by enforcing consequences at home such as eliminating video games or TV for every day he doesn't finish his work and rewarding him with these same privileges when he does his work. I created a laminated behavior chart where she could initial by the day of the week and he would be responsible for taking it to her. Her response: "I do have 20 other students and I can't promise I will get to it". On a side note, I'm a middle school teacher of 128 students and have placed students on the same behavior chart. I'm trying to support the teacher but I keep getting pushback. How else can I support her in the least invasive way?
