When Maura Madigan’s 23 sixth-graders at Keene Mill Elementary in Springfield filled out the “Class of KidsPost” questionnaire, they got into what Mrs. Madigan called a “heated discussion/debate” about what the world’s biggest problem is. Read on, if you want to know their opinion on that issue, plus a few other not-so-serious topics, including their favorite authors, games and ice cream flavors. If you’d like to see your class featured, ask your teacher to go to www.kidspost.com to download our questionnaire, fill it out and send it, along with a class picture, to firstname.lastname@example.org. We’ll feature one class a month throughout the school year. If your class is chosen, we’ll send you a KidsPost Chesapeake Bay poster and KidsPost pencils.
