This handout is a wonderful resource for the middle grades. Essays are an important part of schooling and getting a jump on what an essay should look like is an amazing idea.
This handout includes the opening paragraph (including the thesis statement), the body, and a conclusion. Each section describes what this section of your essay should include as well as what the essay should not include.
*Note* I also put this on a transparency as the students read through their own. I also have the class write an essay together on the overhead and point out what they do correctly and what they do wrong. They love this.
