St Patrick's in a Jar- Gold coins at the bottom, Skittles and marshmallows on top (what a fun and happy gift idea! Even if I forget to celebrate St. Patrick every year. I'm not near Irish, but this is worth using!) Could also use baby food jars!
Good idea for a student teacher! Teacher's survival kit: Animal cookies for when your classroom seems like a zoo. Band Aids for when things get a little rough. Chewing Gum to help you stick to it. Crayons to color your day bright and cheerful, and more.
