This curriculum is divided into levels rather than grades and features extensive use of hands-on materials. The course is workbook-based and employs a great deal of interaction with an abacus and other counting skills. The publisher says that incorporating the abacus into the training allows the teachers “to provide a visual, auditory, and kinesthetic experience” to the student. The workbooks cost around $18 apiece, and the complete elementary kit is over $500.
