This packet details a wonderful strategy for organizing essays called bucketing and gives nice guides for what each paragraph should include. It has a rubric and actual essay from start to finish in order to illustrate the strategy at each step of the process.
When I use this in class I even have real buckets for students (yes, high school students) to actually place their written examples so they can see how their essay will be organized.
This strategy works well for all essay writing, not just in English class.
Thanks for looking, and be sure to check out my other high school English products. I have a PowerPoint that goes with this that may help when introducing the concept to students.
