You should take the creative writing you've done in the past 12 weeks and explain a little bit about some selected parts. Tell them about your favourite part, how long it took you to write, and what your writing was about.
Be sure to include an introduction/hook, and paragraphs 1, 2, and 3. Paragraph 1 will begin the essay. "I'll be reviewing the creative writing I've done in these past 12 weeks, today!"
Paragraph 2 is like the middle, where you're explaining the main parts of the essay.
Paragraph 3 is the conclusion. This is where you will conclude your essay. "...and that was my essay on creative writing!"
Scrooge is such a miser that he won't even allow his clerk to have enough coal to keep him warm. Scrooge's greed is his a downfall because he's so consumed with his money that he neglects the people around him, and when all is said and done, the people are what matter most.
