Upper elementary students learn about rhythm using Legos in music class.  The system, created by teacher Stephen Bachicha, uses color coded blocks to demonstrate time signatures within a four beat measure.  The red Lego constitutes a whole note (4 beats). The students learn that they can use any combination of the the other colors - provided it fits on the red platform.  Students built their rhythms, and then tested them out in class.  A very creative way to demonstrate the relationship between note values and a bit of math all at once.
