This mentor text, "A Slithering Friend", serves as a great example of the components of an effective informational essay for students. The introduction of the essay "hooks" the reader and reveals the main topics that are later developed. The following paragraphs are organized around subtopics. Effective modeling of transitions are included in this mentor text also. The conclusion paragraph restates the main ideas discussed and leaves a final insight for the reader. This mentor text goes very well with The Elaboration Phrases for Information Writing handout on Teachers Pay Teachers.
