I don't think students should choose where to sit because it causes unnecessary confusion.Also, someone might be left out or what if there is a substitute?
Your evidence could be information from a text---it could be a quotation or paraphrase from a reading. It could also be an anecdote or personal experience.
A last thought rewords or wraps up your "main idea", leaving a reader know he/she understands the focus of the paragraph.
For some papers, sometimes you need to write multiple paragraphs. Add a link between them--these "Links" help launch your writing into your next point smoothly.
(C) All in all, middle school students at King should wear uniforms because they enforce positive attitudes, prevent teasing, and help find children when it is really important.
When one considers the benefits this brings to a student’s quality of work, confidence, and safety, then it is clear having everyone wear the same thing is not as terrible as it sounds.
Given uniforms help students produce better work, reduce judgment, and increases children's likelihood of safety in an emergency, then it becomes difficult to argue against them.
To be sure, uniforms will motivate students to produce better work. What's more, they will reduce bullying and increase the chances of lost children being found. Thus, it is clear a standard dress code is wonderful practice.
