The Marshmallow Challenge is a team building activity where students to work together using their given supplies to build the tallest free-standing structure possible. Why Use This Challenge?I have used this activity the first week of school for at least the last ten years. I love it for several reasons. Students love it! It is fun and engaging. Any group can “win” the challenge. Plus, most groups find success!It is a great way to establish group expectations at the beginning of the year.S
