I saw an image done by a professional artist of birdhouses in the snow and it was such a fun colorful image, I wanted to do something like it with my kindergarten students.
We started with a guided drawing of one bird house. I showed them ways to add detail and encouraged them to use lots of color.
They then could add more houses if they wanted to. They also could add birds and nests. When complete, they added dots of paint to represent snow.
