• Giving Change When Payment Is Made With a Dime: The Difficulty of Tens and Ones

    Cynthia Chandler; Constance Kamii
    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.
