A while back I began trying to introduce elements of both Montessori and Waldorf education into our day to day lives. Collecting these shells for the girls to play with was one of the first things I did.
The girls love them. They pour them from one container into another, count them, sort them, and size them. It's not unusual for them to play with their shells for nearly an hour at a time. It's incredible how something so simple and commonplace can bring about so much amusement and learning.
We're looking forward to spring and warm weather so we can go to the beach and collect more shells. I'm also saving our empty glass jars for anything else we might find to collect. I can't wait to see what we find!
