The purpose of this paper is to consider of effect and influence which focus on children's questions core in arithmetic lessons. Therefore we focus the characteristic activities, children’s discussion, children’s writing concerned in children’s questions and theme in teaching unit of decimal division. We consider of effect and influence which focus on children’s questions by qualitative research method.
As a result of our discussion, we have gained several insights such as below.
(1) To promote collaborating learning in arithmetic lesson, children’s questions have effective and central role. At the same time children’s questions generated by children’s discussion take direction of the collaborating learning.
(2) Children’s questions and discussion based on the childen’s question promote to listen various opinion by other people, to catch and interpret other view, to advance thinking in the class. Children’s questions and discussion based on the childen’s question make and foster foundation of understanding about others. Moreover children’s question form meaning renewal about mathematical concept and thinking which they learned previously. But teacher must grasp, interpert and appreciate mathematically about children’s questions in arithmetic as soon as possible.
(3) Through arithmetic lesson move toward from beginning to the end of teaching unit of decimal division, childen’s questions proceed to something universal and mathematical.
