Here is an example flow of what one's speech should look like:
--------
INTRO
Attention Getting Device: A reference to another event that allows the judge to not only pay attention to what you're talking about, but "get it".
Link: Shows how the AGD applies to the topic.
Source: Not necessarily "sourced", but background information on the topic at hand.
Statement Of Significance: Why the judge should care about the topic.
Question: State it verbatim!
Answer: It must apply to every one of your points.
Preview your points: State your three (two?) taglines that show what you're going to be talking about.
POINT STRUCTURE
Point 1/2/3 tagline: An overall view of what this point talks about. A reason for why your answer is true, or an example of why it is true.
On-Top Analysis: Background information that the judge should know before you get into your point.
Subpoint 1/2: They can relate to each other, and together show why your tagline answers the question.
Impact: Relate your tagline back to the question, and say why it relates at all. Use the wording of the question in the impact statement.
CONCLUSION
"So when looking back at today's question:" - Do something like that when moving back to the first spot you stood at.
Question/Answer: Repeat it exactly how you said it in the intro.
Review points: Say your three taglines again.
Relate it back to the AGD: It makes it flow if you do this.
