I never require a certain number of pages. I learned when I did that I would get a lot of words without meaning. Each paragraph is based on the question. There need to be details. Here are examples of what I may require of such a report.
Paragraph 1: Introduce your President with a hook. Example: 'When Abraham Lincoln was elected president, James Bucahnan sent a note to him saying, "My dear sir, If you are as happy on entering the White House as I on leaving, you are a happy man indeed." Mr. Lincoln may have thought that was a very odd note to receive, but as we review his life and his presidency we will learn how prophetic this note was.' Obviously this is above most 5th graders writing abilities, but it gives them an idea of what you are looking for.

Paragraph 2: What was your president's childhood like? (Include birthdate and education)
Paragraph 3: What events in your presidents life led to him becoming president? What did he do that showed he had leadership qualities and made him qualified to be president? How did candidates campaign during this time?
Paragraphs 4/5: What important events happened during his presidency? What new inventions helped the president communicate effectually with the country? How did he travel?
Paragraph 6: What did your president do after his term(s) ended? If he was assasinated, briefly explain the events surrounding it.
Conclusion: Tie everything together.
Teaching the lead and the conclusion will be the most difficult part of the report.
I had due dates for each paragraph. i would make suggestions for improvement. It was much easier looking at one paragraph at a time than the entire report.
PS: We took almost a quarter to do our research report, but they also learned how to do a works cited page, how not to plagerize, writing skills such as transitions, etc., speaking skills (presenting their projects), reading timelines, comparison of US events with world events, primary sources, etc. I covered an unbelievable number of objectives in both LA and SS.
