One of our preschool weeks is "A is for America." In honor of our nation's birthday, I'm posting a few activities that are "purely" American. The first is a set of 3-part cards about American Inventions. I tried to include inventions that most kids would encounter frequently and were nonviolent (so no machine guns or atomic bombs). Of course the category of inventions is quite large and could include many more cards. There are 16 inventions on this file. Later, I'd like to add some more packs. All of the pictures are from Wikipedia.
