I have found this resource to be invaluable in the past. Each student has this checklist laminated and stuck to the top of their desk. Students are encouraged to read through and complete the checklist at the completion of every set task. When students are accustomed to doing this, you are free from questions like "What do I do now?" and "Where do I put my work?". It also serves as a great reminder to students to proofread their work before handing it in for marking.
