Ground rules for talk
One way to facilitate the development of a supportive environment where children can articulate their ideas freely is through the negotiation of ‘ground rules’ for talk. The Thinking Together website (Dawes, 2010) has some very useful resources for encouraging children to consider how talk is used in classrooms and activities for developing ground rules for talk with your students.
