You can really put anything in a binder. You can use worksheets and stick them in pocket protectors and use dry erase markers. You can use velcro assembly tasks. Yo can also use pockets to store manipulative for extended activities. Whatever it is, I love to squeeze it into a binder. Yes, call me binder obsessed!
One of my favorite activities are my TEACCH Binder Tasks for the whole year. These basic skills are stored in a binder for each skill and are easy to change out each month. This allows for easy repetition and consistency for our students on the spectrum. If you want to check those out in my TPT store, click here.
I also like ziploc baggies because they are easy to bend and store. They are not as "restrictive" as storing binders. I stick all of the binder tasks in ziplock baggies inside of my monthly bins. This keeps everything organized and out of the way until the next school year.
Binder tasks are intended to make your life easier. They require no planning and are effective hands on activities for your students. Storing them should not be stressful!
