Teaching Children about the Inverse Relation between Addition and Subtraction
Nunes, Terezinha; Bryant, Peter; Hallett, Darcy; Bell, Daniel; Evans, Deborah
Mathematical Thinking and Learning: An International Journal, v11 n1-2 p61-78 Jan 2009
Two intervention studies are described. Both were designed to study the effects of teaching children about the inverse relation between addition and subtraction. The interventions were successful with 8-year-old children in Study 1 and to a limited extent with 5-year-old children in Study 2. In Study 1 teaching children about inversion increased their success not just in Inverse problems (a + b - b = ?) but also in Transfer complement problems (a + b = c; c - b = ?). (Contains 1 footnote, 3 tables, and 1 figure.)
