Strategies for comparing decimal numbers with the same whole-number part

Baturo, Annette R. & Cooper, Thomas J. (1995) Strategies for comparing decimal numbers with the same whole-number part. In Atweh, Bill & Flavel., Steve (Eds.) Proceedings of the18th Annual Conference Of The Mathematics Education Research Group Of Australia, MERGA, Northern Territory University, Darwin, North Territories, pp. 73-79.


The strategies employed by 130 Grade 5 Brisbane students in comparing decimal numbers which have the same whole-number part were compared with those identified in similar studies conducted in the USA, France and Israel. Three new strategies were identified. Similar to USA results, the most common comparison errors stemmed from the incorrect whole-number strategy in which length is confused with size. The findings of this present study tend to support Resnick et al.’s (1989) hypothesis that the introduction of decimal-fraction recording before common-fraction recording seems to promote better comparison of decimal numbers.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
