I suggest printing the powerpoint using 2 slides per page, then cut them out and use them as cards for the "I Have…Who Has…?" game. That way, the cards are big enough for the students to read them at their individual desks. Then display the powerpoint on the screen as students play so that they are all able to see the questions. When my students finished the game in my class, someone yelled, "Can we play again? That was fun!" I knew my job was done.
