Giving Change When Payment Is Made with a Dime: The Difficulty of Tens and Ones
Chandler, Cynthia C.; Kamii, Constance
Journal for Research in Mathematics Education, v40 n2 p97-118 Mar 2009
The purpose of this study was to investigate children's construction of 10s out of the 1s they have already constructed. It was found that, for many younger children, a dime was something different from 10 pennies even though they could say with confidence that a dime was worth 10 cents. As the children grew older, their performance improved. (Contains 8 tables and 4 figures.)
