The Conversation Tree is one of the coolest social skills activities I have done with my students and is very effective especially those on the Autism spectrum. Cut out each piece of the document. Each student in the group gets to be a different color. Place the top of the tree and the bottom pot at the top and bottom of your white board. The students will begin by starting a conversation with each other. As they participate appropriately (the definition of appropriate you can decide what that is for your students), their color square will be placed on the tree. As each student participates, it becomes the tree trunk. The idea is to make the tree as multi-colored as possible. If a student talks out of turn, changes the subject, does something inappropriate, doesn't listen to the others speaking etc. the branches are added because the students are "off-topic". I explain to my students that everyone comes from a different background and has different perspectives on life. As we get to know each other our relationship grows (making the green part larger). It is a wonderful visual for your students to realize what their conversations look like!
