Building a model, map or construction. When students build a map or a model, it is not the final product that is so valuable as the doing of it. A model of the Bastille to illustrate the fourteenth of July. A three dimensional map of a district, province or even a small country, laid out on a table, could be a long term project, where mountains are made from paper mache. When students build such a map or model, they identify with it, and it becomes more easy to get them interested in characteristics of it. Important here to not insist on too precise a replica; the building of it is more educational than the final product.
