This set is perfect for a class of 20 students. It includes a set of lesson plans that walks you step by step through the teaching process using five sets of 31 blocks representing the five most common note and rest values. Your students will immediately understand the relationships between these note values as well as the "silent" notation on the backs. Three time-signature frames will help students compose in 2/4, 3/4, or 4/4 time. Rhythms are easily read by simply saying the colors.
