You can also use a “gimic” which will help you to remember….here is how….

I taught a seminar once and used a gift box full of items. Pulling out an item at a time, I used them as part of my talk.

You could do the same thing. Each “item” will remind you of the next point…an easy way to remember your talk, and also interesting to your audience.

If you do something like that that makes them curious, you have their attention. Try it, it works…and is the easy way to present your talk. Five minutes is very little time….maybe five items…talk for a minute each.

Word of advice from a former professional procrastinator…don’t wait until the last minute.
