In kindergarten we have been studying 2D and 3D shapes.  The children in the class were invited to bring in two 3D items from home to use in creating a 3D sculpture.   I also provided some extra items so that we would have some of each shape (cylinders, cones, cubes, rectangular prisms and spheres).  The students were divided into 3 groups and took turns working with me to create some amazing sculptures.  See for yourself!
