Oh, this is one of my pet peeves. So many people believe that if a child needs advanced work, that just means they should be loaded down with more of the same. Last year my son's class spent about five months learning to add two digit numbers, a skill my son had learned before kindergarten. I repeatedly spoke to his teacher and administrators about the fact that he was not learning anything, but it took until April for anything to change. Instead of a sheet of 20 or so addition problems, she started giving him multiplication problems - on average, about 100 problems per night. The drills helped him, since he was in the process of memorizing his multiplication tables. But I got the impression she was trying to prove somehow that he was not so advanced.
He did all the homework. But that incident, combined with the snarky way she spoke to me and my son, caused me to complain loudly about her to the administration and school board, and I have made it crystal clear that when my daughter gets to that point, she will NOT be in that teacher's class.
