Children's Understanding of the Principles of Covariation and Compensation in Part-Whole Relationships.
Irwin, Kathryn C.
Journal for Research in Mathematics Education, v27 n1 p25-40 Jan 1996

Only 7-year olds were able to use covariance and compensation in the purely numerical context of derived equations. (Author/MKR)
