I forgot to mention DS6 gets frustrated when he cannot learn 'more' after quickly grasping an idea. I gather from the teacher it may not be appropriate to move on for whatever reason. I wonder how fast my son could learn if given the environment to keep learning if he is given individual attention! Oh, well, it is only the second week of school and I will be in touch with his teacher. I think he is her biggest challenge. He learns so fast!
