Subject object pronouns game
[In an effort to keep track of useful materials--so I can find it again when I need it--I'm collecting links to stuff that I've had good luck with using in class. I'm indexing it, along with my own materials, over here and here.   The above link is to materials that I've used successfully for a lesson on object pronouns with young children.
 The link above I used with young children studying the difference between subject pronouns and object pronouns.  It was used in a classroom that had a projector and an interactive whiteboard.  The class was divided into 2 teams, and competed against each other.]
