This assignment gives students clear instructions and a structure for writing a four paragraph letter all about themselves. It's intended to be written in letter form and addressed to the teacher, but could be modified.
Included is a sample letter, graphic organizer, and rubric.
I've used this assignment near the beginning of the year to learn more about the kids. I've also thought about using it toward the end of the year for students to introduce themselves to their new teacher for next year.
