Creating "Markers" Within A MP3 file

Hello! I am recording a long passage for my son to memorize. He will need to learn it in parts. I am not versed in the technical terms, so my wording might not be correct. My goal is to create “breaks” within a single MP3 file from which he can skip to and from, rather than recording a series of MP3s which he would have to go through. Is this possible, and if so, how do I go about doing it?

I am using Audacity v2.0.6 on Windows 7 Professional, 64-bit. Thank you!
