We read "Frosty the Snowman" and then made marshmallow snowmen and s'mores. 
The girls really enjoyed Lois Lenski's book "I Like Winter". Our corresponding activity was making gumdrop trees. We ran out of gumdrops on the last row and had to pilfer some from the back to finish the top off. Anna and Lauren really had fun with this craft but wow, that sugar is messy!
We loved making these stacked Christmas trees. One of our favorite books this year has been "Mr. Willowby's Christmas Tree". It's such a cute story about a Christmas tree that serves many different types of families
