Folk Tale Letter Writing
Grades: 2 - 4
Ongoing? No
Look at the Big Bad Wolf in a whole new light, and encourage your Language Arts students to express their creativity at the same time! This site outlines an impersonation project in which younger students (2nd to 4th grade) read a fairy tale and write a response directed to one of the main characters. The older students, using an approach like a literature circle, discuss the issues and character types found in the fairy tales, then they respond as a group to the particular issues that the younger students have raised in their responses. Teacher resources include ideas for eliciting rich and fruitful responses to stories by students.

Letters to Santa
