This study investigated the participation of children at the writing center in their classroom during free choice time. For this study, four and five year-old children in the classroom were observed during 20 free choice times, each one of which was one hour. I developed a coding system related to the activities that were intended to develop the children's writing skills. I observed and coded 69 children in the writing center. How these children used the writing center was coded with respect to frequency, gender, and activity. The findings showed that children spent between 10 and 20 minutes in the writing center; only 12 of the coded children were boys and 57 of the coded children were girls. The children were observed to prefer spending time in the centers adding interesting materials. One time the teacher added new materials and one time she participated with the children in the writing center across the twenty observations. In the writing center, children mostly did drawing activities (84.1%) and the least they did was writing and copying with chards activities (14.4%). The findings show the importance of using materials for supporting children's writing skills, because more than one child came to writing center, and more than one spent time in this center. Furthermore, this finding shows that children preferred mostly drawing and pointing activities in the writing center.
