Whenever I have my students create a brochure for a project, I am very specific about what should be on each page. I have developed an easy template which always me to type in the information in each section.
I have attached the template with an example. At the top is the grading rubric (a very simple one). Students fold the paper and then use this as a guide to each page.
The example is Ancient Rome and Early Life in the American Colonies.
