Une Introduction Non Classique aux Algorithmes d'Addition et de Soustraction (A Non-Classical Introduction to Algorithms of Addition and Subtraction)

Analyzes a didactical sequence for the teaching of addition and subtraction procedures and algorithms. Uses didactical procedures by children in problem solving activities in order to gain a better understanding of the interaction between numbers, numeration, and operations knowledge which are involved in the construction of addition and subtraction procedures and algorithms, and to relate children's knowledge acquisition to didactical situations.
