Give each student a WS and go over the 5 objects that they need to draw in the top room. Give students around 5 minutes to draw all the objects into the top room picture. Don't allow too much time for drawing as the focus should be on the speaking portion of the activity. After the objects have been drawn, pair up the students and have them decide who is A and who is B. Then have A describe where all the objects are and B will draw them in the lower room picture. Once B has finished drawing compare A's original room to B's copied room. Then switch. Here is the convo I had students use for this activity:
B: Where is the ~?
A; It's (by, in, on, under) the ~.
