After we read the story we went on a walk around the neighborhood to try to spot out some of the pretty flowers we had seen in the book. We talked about what colors they were, what shapes they were, how they smelt, and also about how God created them for us to enjoy.
A couple days later we read the book again and decided that we should make our own rainbow gardens. We took a piece of white construction paper and each colored the bottom of the paper brown for the ground, and then colored green flower stems coming out of the ground.
Before we assembled our flowers we sorted our shapes by colors and then went through naming all of the different shapes. Since my youngest is preschool age, it was perfect practice for him.
