Children's Relational Knowledge of Addition and Subtraction.
Baroody, Arthur J.
Cognition and Instruction, v17 n2 p137-75 1999
Two studies pursued theory that knowledge of addition combinations facilitates learning of subtraction combinations. Study 1 involved 25 kindergartners and 15 first graders in a gifted program; study 2 involved 21 first graders in a regular program. Participants responded to two pairs of problems. Findings revealed that the complementary relationship between addition and subtraction is not obvious to children. (LBT)
