We started the day by making some ducks of our own.
The pattern for these ducks can be found here. I loved these patterns as not only were they cute but we talked about shapes while coloring and cutting these out; star-feet, heart-wings, etc. We then read Bluebird's Nest by Dorothea DePrisco with illustrations by Jo Parry. Obviously this book is not about ducks, but it is the cutest story about a bird building it's nest and other animals helping out. And the nest actually grows throughout the book.
We fed the ducks
we ran up and down the hills
That evening when Eric got home and Lucas told him why the ducks are the color they are and lots of facts about ducks; I knew the day was a success.
