Below I provide audio files in .wav format for William Mounce’s introductory grammar, Basics of Biblical Greek (BBG). I read the vocab words at the end of the chapter, some of the exercises from the Mounce Workbook (WB), and sometimes some of the paradigms in the lesson.
Below is a Song to use to memorize the case endings of the 1st and 2nd Declension. One of my Greek classes (at The Bible Seminary) sang this to the tune of “Jesus Loves the Little Children”; play this over and over, sing along with it, and you will learn the case endings! To follow along, you need to have this chart open in front of you; write these case endings down as you sing the song to yourself: https://biblicallanguages.files.wordpress.com/2009/05/all-case-endings-1st-and-2nd-decl1.pdf
