Abstract
The purpose of this study is to make a “Mathematics Play Learning Program”
for 3, 4 & 5 year olds. In this paper, I aimed to investigate the effect of cognition
investigation that incorporates the guided play for 3 year old children. In fact, I
made a cognition investigation that incorporates the guided play. And, it was
carried out the investigation of every month in the home. As a result, it was
possible to find some characteristics of a child's cognition. Furthermore， it was
suggested that itself may become a play learning to improve the mathematical
cognition of a child.
