This is Unit 2: Time Signatures. Instructors should not move on to Unit 2 until all basic rhythms and concepts in Unit 1 have been mastered.
Unit 2 goes through the concept and breakdown of time signatures, but in a different way than you're probably used to. I hate just teaching rote and only exposing students to "4/4" time. I feel like they don't really understand why rhythms work the way they do when you do that. Instead, I created this concept for teaching time signatures, including the concepts of "pure" and "impure" form. In this way, students understand how to dissect and recreate any time signature, with any rhythm. It's amazing to see a student (who had no musical training before my class) explain "2/2" time or "9/8" time with as much ease as the common time.
While these notes are only one page, I give you some examples and encourage you to do tons of repetition. Get creative and let the students really start to "compose" rhythms of their own!
