I have two students who are so absolutely low. They do not know their colors, they have no concept of what a letter is or a number is, they have a hard time comprehending anything I am saying. I don't know...am I expecting too much from them? We have been in school for over three weeks now and I am still trying to get them to recognize the letter A and the number 1. I would think they would get it by now. I do a lot of extra things with these students with helping them with their letters and numbers. I gave them a DIBELS test and they both scored 0. I've never had that before. Is there something I'm missing?
