Team Building Task-The Cup Challenge - take a rubber band and tie 6 strings to it (though I think 5 would work if you want smaller groups). Participants must use only the strings to move 6 cups into a pyramid formation. You can make this a competition between the groups or give them harder cup moving tasks.
Building a classroom community is very important and is an indicator of success. Icebreakers and other activities are important to implement during the first days of a new school year. It is important for all students to feel welcome and a part of their small community which actually a part of an even bigger one. Feeling comfortable will help create resilient learners that have confidence in sharing their ideas without fear of being judged.
