LessonWriter.com is an awesome tool that allows you to quickly create the following activities for any article or story:
vocabulary dictionaries and questions
grammar examples and questions
LessonWriter essentially creates a worksheet, which many teachers don't appreciate because worksheets are not usually rigorous. However, I think that LessonWriter might be a good activity for your students to create assignments based on articles they read. This tool can be effective not only in Literature/Composition classrooms, but also in any classroom that reads texts from the web. Try it out and tell me what you think!
