The document provides instructions for a student to write a friendly letter from the perspective of their past English Language Arts teacher to their current ELA teacher. The letter should be 1-1.5 pages and discuss what the past teacher would say about the student as an ELA student, including what they liked/disliked in class, personality traits, memorable events, and potential warnings or praise for the student. Writing the letter from the teacher's perspective requires conveying their unique voice and personality to convince the current teacher it was written by the past teacher.
