Teaching children about the inverse relation between addition and subtraction. (English)
Math. Think. Learn. 11, No. 1-2, 61-78 (2009).
Summary: 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 = ?).
