Abstract
What are the effects of studying 1, 3, or 5 place-value systems of numeration? Each of 3 experimental 4th grade groups received 30 minutes of instruction for 9 consecutive school days. A 4th group served as control. Statistical procedures included multivariate analysis of covariance. The results suggest: for the group under consideration (1) a study of the decimal system alone tends to be just as effective as a study of 3 or 5 systems in promoting understanding of the decimal system; (2) a study of either 3 or 5 place-value systems of numeration appears to be more effective than a study of the decimal system alone in promoting understanding of the general principles of place-value systems of numeration.
