To set up the "Four Square Rhythm" activity, you must put four boxes made of tape down on the floor--one is blue, one is white, one is green, and one is yellow (each color box represents a different note value).

This activity helps students practice switching between notes of different value and understanding the relationship between half, quarter, eighth, and sixteenth
