Construct the memo using standard headings: To, From, Date, Regarding.
Orient the reader by stating the topic as well as which assignment the memo is addressing. Briefly address your purpose and individual slant on the subject. This will be the first paragraph of your memo.
Describe the process you followed to complete this draft of the assignment. Note hurdles and discoveries and indicate resources that you found helpful. Indicate what draft you are working on---first, second, final---and describe what you like best about this version. If it is an early draft, indicate what continues to need work. This will be your second paragraph.
Indicate several specific aspects of the paper on which you'd like your instructor's assessment. These might include organization, content development, quality of the research or style. You can also invite a certain style response from your instructor, such as encouraging, direct or critical. This will be the closing paragraph of the memo.
