Note Knacks® is based on visual and tactile learning in conjunction with written and community learning. The Note Knacks® system crosses disciplines and teaches broad meta-concepts in math, such as fractions and algebra, as well as comparative and relational writing skills through the use of musical and graphic notation. The curriculum is particularly effective with Kindergarten through Second Grade children, but it also expands easily to higher grades. Rhythm Band Instruments is the exclusive manufacturer and distributor of Note Knacks®.
