Recycled Valentine Challenge
I teach fourth grade, and never have enough time to dedicate any to making Valentine holders, so I created an optional home project where kids try to design unique holders out of recycled materials. Kids create reward categories like Craziest, Prettyist, etc. I always keep a handful of white bags on hand for those who did not chose to do the project, but never have more than a few, and those are usually ones who have forgotten theirs.
