Abstract
The purpose of this study is to show how very young students develop views of distributions, focusing
on aspects of students’ conjecturing distributions, in order to look for the possibility of teaching related to
distribution for the lower grades at elementary school. For this purpose, first, the study designed and implemented
the teaching experiment for 2nd graders. Then, the study analyzed students’ views of distributions with the
framework based on the SOLO Taxonomy, focusing on aspects of students’ conjecturing distributions in the
teaching experiment. The analysis showed the following:
- Some students could utilize the awareness of variability as reasons for conjecturing distributions.
- Students’ views of distributions were undeveloped at the beginning. Many students, however, could develop
powerful views of distributions by conjecturing them based on the process of growing samples or with graphical
representations.
