Subtraction Songs Kit w/ CD
Learn your arithmetic facts painlessly, through song! After the vocalist sings you through the facts in echo style, songs are sung without answers, and it's your turn to solve the problem! Each day practice a different "song." In just 9-12 days, you'll have these facts memorized with very little effort. Play again and again for review and drill. Kits each include a CD and reproducible workbook.
