I use this activity at the beginning of the year with my 6th graders. I've used it as low as 4th grade successfully, but I imagine even younger students could complete it at their own level.
My 6th graders particularly love it when I include music, and this lets them know right away that I'm a music-loving sort of teacher.
You'll need access to the song, "I Got a Name" by Jim Croce. Students will listen to the song and relate each of the 3 verses to an aspect of themselves. Their name, their "song," and their dream.
