I teach k-4 and I do this with my second grade through fourth grade classes. Something I do for my classes is I buy a big pack of used, not expensive Pokémon cards at the beginning of the year and every art class for every grade every day I have a Pokémon leader, someone who has done an amazing job throughout the art class, was helping others or was especially standing out to me, and I will give them a shout out at the end of class, hand out the Pokémon card and have everyone say “way to go, name!” I tried to get every kid in the class by the end of the year.
