Mastering single-digit arithmetic during school years is commonly thought to depend upon an increasing reliance on verbally memorized facts. An alternative model, however, posits that fluency in single-digit arithmetic might also be achieved via the increasing use of efficient calculation procedures. To test between these hypotheses, we used a…

The relative efficacy of two approaches to teaching basic multiplication facts to third graders is examined. Support was indicated for the thinking strategies approach. Results also indicated it was possible to train teachers in two days of inservice education. (MP)
