I teach 4 different science classes (6 classes total because I have multiple sections) ranging from 7th-12th grade. I want to check some assignments on completion, which I have seen in action but haven't tried myself (I'm a new teacher....I've had long-term sub jobs but this is my first full-year job). Just looking for some ideas about what to do when someone doesn't complete the work the first time and they decide to make it up later. I plan on going over the answers with kids the next day so they can check their work, but that means that the answers are floating around and easy for the student to attain. Does it mean making an alternate assignment, or is there another way? Thanks!
