The students practise the use of "there was" and "there were", furniture vocabulary and prepositions of place (on, over, in front of, behind, etc.) The students must folder the worksheet in order to see just the room. Tell them that they have 2 minutes to memorize what is in the room. After that time they must write sentences about the room without looking at it again. Then let them see the picture again to check if they were right. This activity works better when the students work in pairs.
