The CalcuLadder 2 workbook includes 12 copies each of Levels 17-32 of the CalcuLadder drills, plus Guide, QuicKeys, and Achievement Record. The drills have 3- or 4-minute time goals. They cover multi-column and multi-digit addition and subtraction with carrying and borrowing, and the multiplication tables through the "9's." Successive drill Levels review earlier material while introducing new facts.
