I use One-Zip plastic bags to help organize my art activities. I copy patterns on construction paper and place them in a bag. I then tape a finished copy of the project on the outside of the bag and place it in the students' art activity center. They are able to complete the project on their own using the model and patterns provided. I also use these One-Zip bags to store a set of supplies for each student's personal use. I can store an extra set of clothes for my children in the larger two-gallon Ziploc bags. These bags work well for an inexpensive means of keeping everything neat and organized as well as teaching children responsibility for taking care of their own materials.
