In this study, it is aimed to present an activity to develop students' creative thinking skills. To that end, 'Take Out One-Add One Activity' has been implemented. The activity has been applied to six gifted and talented students attending the Individual Talent Recognition Program at the Science and Art Center. In the first stage of the activity, students have been given visuals showing the change of headphones over the years. Students were provided to see the change and development in the headphones. Then, a pencil has been chosen as an object to use in the activity. An activity form has been handed out to the students. Students have been asked to remove a tool or feature from the pen and add a new tool or feature. Written opinion form has been used to determine the opinions of the students about the activity. The observations of the supervisor teacher have also been taken into account. Content analysis has been performed on the obtained data. The reliability among encoders was determined as .85. At the end of the activity, it has been concluded that the students liked the activity and that the activity contributed to the development of creative thinking skills.
