Read Write Think's Compare & Contrast Map is a template for creating a comparative essay. Using the template students are guided through writing three styles of comparison essays. To get started students identify two things that they wish to compare and or contrast. Then they choose if they want to write a "whole to whole" essay, a "similarities to differences" essay, or a "point to point" essay. Whichever essay type they choose, students are guided through the types of information they should put in each part of their essays. When their essays are complete students can share them via email or print them.
