抄録

This study aims to examine the relation between objects and counting during the process of learning subtraction based on ten-structure. I confirmed how calculations are gradually mastered based on ten-structure by the use of objects through the introspective observations of 1^<st> grade elementary school students. Depending on the type of objects used, children use counting as a device or use methods other than counting to carry out calculations. In subtraction, when children make a judgment that counting using objects is possible, they rely on calculations based on counting. When children decide that counting using objects is not possible, they convert to methods based on ten-structure by using retrieval or mental calculation. I present the idea of a strategy conversion model by using different objects.
