In this video clip, Oliver is stacking large wooden frames that can be securely fitted together by placing the legs of one frame into the notches in another frame. He says, “Put it on the tower,” as he lifts a wooden piece and places it on top (00:03). His tower at this point is a randomly placed pile of these wooden frames. Oliver uses pretense to enhance his role as a builder. He says, “I need to hammer this” (00:06).

Perhaps he notices that his pile for frames wobbles a bit. He transforms a soft cloth monkey into a pretend hammer by swinging the monkey with great force and making a sound effect, “m-m-m-mamps” (00:11). It is interesting that Oliver does not select a rigid object to represent the hammer. He may believe that a hammer is best characterized by the swinging action, rather than the hammering sound. Or, he may recognize that swinging a rigid object with similar force could cause the tower to fall, so he makes a practical choice.

Oliver uses occasional self-talk to guide his work. He removes a wooden piece from his pile of frames and says, “That” as he sets it on the floor, perhaps designating the start of a new structure (00:17). As he moves the second wooden piece into place, he says, “Like this” (00:25). Later on, he notes his surprise by saying, “Whoa!” when a wooden piece tips and does not align with the piece below (00:56). Oliver knows about how the wooden pieces work. He carries the second wooden piece with “legs” extended (00:22) and ready to be inserted into the empty notches of the piece below.

The wooden pieces can be stacked securely in either orientation – legs down or legs up. Oliver may assimilate the protruding “legs” to a chair or stool and thus orients them downward. He works to add a third level by seating one leg and then wiggling the wooden piece until the other three legs shift into place (00:38-00:44). Oliver notes his progress as he steps back to observe the tower (00:44-00:46), before reaching for another wooden piece. The size and inter-locking design of the wooden frames enable Oliver to build quickly. Soon his efforts yield a tower that is taller than he is. Oliver raises a wooden piece above his head and stands tall in order to add it to the top.

Although the wooden piece stays in place and does not fall, Oliver knows the placement is not quite right. He says, “I need the stool for that” (01:43). Good Night Ringtone Free Download.

Oliver removes the wooden piece and again says, “I need a stool for this” (01:46). At the beginning of the video, Oliver labeled the collection of wooden pieces “the tower” and did not object to their unaligned configuration. Here, he applies different rules. The teacher (holding video camera) encourages peer collaboration. She works to help Tommy (off camera) gain entry into the play by saying, “Do you want to bring that (stool) to Oliver?
