The two activities in this lesson are designed to illustrate to pupils the main features of structures using sheet materials. The first activity shows the names of the main parts of a model house. The second enables teachers to show pupils how to join sheet materials simply. Teachers should introduce, explain and discuss the following words and concepts with pupils: door, window, floor, chimney, wall, stairs and roof. Both activities show a complete model first and teachers should discuss with pupils how to disassemble and then reassemble the product.
