Students in Carol McLaughlin's second grade classroom are participating in a yearlong Global Math Challenge using Twitter. Her class signed up to challenge other second graders across the world with a daily math problem for a week. In response, classrooms from all across the world tweeted their answers explaining their strategies using the hashtag #gmttc2. Classrooms from Kindergarten through High School may sign up to participate at gmttc.blogspot.com.
