What's in the mail game?

The girls love getting packages in the mail so I thought this would be a fun game to play. I added rocks, coins, a book, a blanket, marbles, and pencils to separate boxes and envelopes. Jem had to squeeze and shake the mail to figure out what was inside. Both girls gave good guesses and enjoyed this easy activity. I think we'll also do this on our next road trip in the car.
