Since you generally don't mention your salary on your Resume, simply put it as a regular work experience. You may want to specify "full-time" versus "part-time" but it doesn't really help. This is only if someone asks you about this specific experience that you can give more details.

Remember, a Resume is a showcase of things you've done and would like to share with the world. We don't mention everything on a Resume. As long as everything is legit, you're good to go. Avoid going into too many details as it makes it confusing for a recruiter and you may get penalized for that. Show case what you've done during your part time experience under the same employer (when you were full time).
