Our teacher decided to do away with this effort. All the children in the class were given white sheets of paper with black lined hearts( featured below if you would like to copy) and have to say something nice about each child in the class. They are allowed to decorate the hearts with crayons, colored pencils, etc. Anyway, there no is capitalism involved in this transaction (no economic stimulus activity here). No independent, unique, creativity in design, card selection, candy choices, etc. Also, thinking of something kind to say about the class bully, is really a lesson in "putting on a false smile and digging deep for a kind thought".
Anyway, my older daughter said---that teacher took all the fun out of Valentine's Day!
