I was inspired by Kelly Jensen at Field Acquisitions (here & here), Ms. Kelly at the Library, and Jenni.
I've done this event three times.
The first time we did the following: chocolate pictionary, M&M's sorting, identify the chocolate, whopper races, and Hershey Kiss races.
The second time, I added a chocolate memory game (thanks, Pinterest!) and chocolate tasting, but dropped identify the chocolate.
The third time I added a chocolate toss and a M&M relay.
The Whopper race is the most fun and I'm always looking for new games to add.
