I am a first year 3rd grade teacher. During my math lessons my kids participate and seem to know what is going on. I can go around the room and ask individual questions and every kid will answer correctly. I pass out the papers and we always do the front side together. The back side they do alone. It is EXACLTLY the same as the front, same concept, just different numbers. I get to grading the papers and I have a couple kids who will BOMB the paper. I have started giving these papers back to correct. I make them attempt to correct it by themselves once and if they still don't understand we discuss. My question is should I give partial credit back for corrections they do on their own? What do I do to make these certain handful understand?
