Every year my co-teacher and I have a "Tissue Box Homework Pass" where if the kids donate a tissue box to the classroom, they get a homework pass that they can use in any of the 4 subjects. It's worked out pretty well in the past... I usually write "Thank you, (student name)" on the tissue box to give them credit for bringing the tissue box in.
This year, one of my students always brought in a container of anti-bacterial soap for the classroom. I always gave her a "Tissue Box Homework Pass," but I figured this year I would do a general "Donation" homework pass to encompass anything the students bring in for the classroom.
And yes...I did use Vistaprint again... same deal as the other homework passes I blogged about!
