To add labels to your posts, simply put your desired label into the box in the bottom right-hand corner of the post page. Use labels like "400 word essay", "poem", "book review." For extra work, that is not required for the portfolio, use the label "extra."
Once you begin labeling posts, you must also add "Labels" as a gadget on your sidebar. Remember, to input a gadget, simply click "customize" or "layout" and then add a gadget. Within the labels gadget, you may choose to add your labels as a drop down list, as Antoniya has done, or as a word cloud, as Deia has done.
Everyone MUST use labels to organize their final portfolio, so it's best to start now!
