The purpose of this study is to investigate the effect of toddler’s social skills through the use of board games in peer
activity. An at-risk young child who attended a regular day care center located in Seoul was selected for this study. Of all single
case experiment, the study has been designed by the way of ‘multiple baseline design across behaviors’, a record technique of
target behavior. The experiment was implemented by baseline, intervention, maintenance, and the researchers observed a child
for half an hour to measure and count numbers of cooperation, assertiveness, and self control behaviors with frequency
recording, after the intervention of 20 minutes-board game. As a result, peer activity using board games provided positive
influence on toddler’s cooperation, assertiveness, and self control behaviors, which can be called ‘social skills’. Thus, this activity
can be considered as an efficient intervention at acquiring desirable social skills for at-risk children.
