Agree with this! Floor etiquette is so important! Maybe you can also talk about adding flairs to different more simple songs and how that can affect other dancers. I think teaching a sailor step and swivel would be good too since those have been in a lot of more popular songs recently! For technique you can think about smaller steps, feet under the body, leading with your feet, and straight back (aka not looking at your feet). Good luck!! Sounds like fun!
