This lesson is from Purple Twig so click over to read the original post. The children loved working on this and I was happy that they could try both painting and collaging and end up with one beautiful picture. We talked about radishes, turnips, onions, potatoes, beets, and carrots, and it was helpful to have our school vegetable garden right outside the window! Lots of possibilities for integrating gardening themes!
Here are a few of my favorite children’s books about gardening: The Curious Garden, A Seed Is Sleepy, And Then It’s Spring
