My room runs on this TEACHH-like system! Each student gets their own "menu" and independently navigates the room, working their way through their own IEP goal-related tasks at their own pace.
Just print and glue pages 1-3 to the front and insides of a manila folder, laminate, then cut, and apply velcro to the square pieces and insides of the folder. Just adhere a second set of the square task pieces to the activities you want students to complete. I also keep the table on page 11 for my own records, to more easily designate which tasks are appropriate for each student and assign the week's tasks quickly. In this document, I've included several different types of activities we have in our classrooms (file folders, workboxes, flip cards, crate tasks, etc.), but you can easily sub out your own and use shapes/colors instead of numbers for kiddos who do not have number matching/identification skills yet.
Students can then move activity pieces from the "to do" to the "done" side as they complete activities throughout the week. I have my class put finished tasks in a basket, to be checked by me, and if anything needs to be corrected, I'll just mark the incorrect problems with an X and move their task piece back to the "to do" side, for them to correct the next day.
This system increases students' independent work skills, time management, and builds executive functioning organization.
