One of the projects in the 3rd grade at the_child's school is that each kid has to make a model house that represents the way people live somewhere in the world. They also write a report to go with their house. The work is very interesting, some of it cute, and some of it compelling.
the_child's handiwork, with a considerable parental assist.
Some of the other third grade houses. I particularly like the marshmallow igloo.
