My tips:
Look at the photoalbum:
http://picasaweb.google.com/Sean.Pigg/MimsAndSeanSHouseWith an elementary/pre-intermediate student these pictures could be used to teach:
1. The vocabulary of house and living.
2. Present simple by asking: What do they usually do in this room/ place? (interrogative, negative too)
3. Present continuous, by using the pictures with people, asking What are they doing?, etc.(interrogative, negative too)
4. The use of There is, There are. (interrogative, negative too)
5. Countable, uncountable nouns- much and many- Many chairs, much space
6. Prepositions of place.
7. Comparatives and superlatives- This room is bigger than that one. This is the largest room., etc.
These are just a few ideas. Have fun!
