5th grade Math

Good afternoon....we took a test today in math so we didn't have homework. BUT I gave back some papers for some to correct. They are not reading directions or skipping problems. I need these redone and handed back so I can put a grade down for them. If I don't get them back it will be a zero in my grade book. This is the last week that I'm going to be handing back this many papers. I can't keep double grading. I have given them a chance to learn the routine and learn how my class works. I do understand sometimes you have a bad day and miss a lot. I will make some exceptions. But please work with me to make sure they are completing their homework and weekend assignments.
