Here's a St. Patrick's Day gift that your students will love: A free homework pass to use specifically on a journal! I used this either as a reward or class gift, and the students never complained. You can modify this pass for a specific subject/class, though I do recommend that you copy it on green paper (if available).
I also have a St. Patrick's Day Homework Pass available on this site if you do not assign journals on a regular basis.
Thanks for viewing this document; feel free to check out the others I have listed on TPT. If interested in something you don't see, please contact me: firstname.lastname@example.org
