Houses were made using the cardboard boxes. We had been using yarn to make telephones (paper cups & yarn) so yarn was added to the house so it could be pulled along. One of the children who comes from Poland made one for his cat. When his dad came to collect him he told me that it was for in the snow. It was a sled. Creativity, background knowledge, use of materials, size, shape, length, and so much more from making a dino house with recycled boxes & yarn.
