| Outline of Final Research Achievements |
We attempted to clarify how “assuming proportion and multiplying and dividing” starts to be recognized in the child. As a result, we found one process regarding “how the multiplicative proportion of the decimal proportion is recognized with the way multiplicative proportion and divided equal proportion functions”. Furthermore, by specifying that there is a reality of the divided equal proportion in the range of integers being not recognized, we considered that focusing on “homogeneity” is important. Along with that, the subject with a minute framework for further analysis and examination for focusing on the homogeneity.
