Let the booing begin! Yes, it's that time of year. Classes are getting booed and booing others. What does that mean? Fun Halloween surprises are dropped off outside of a classroom. The recipient doesn't know who left the treats! that is left outside someone’s door without them knowing who left it. Print off the 2nd and 3rd page and include them with a delicious treat. Once a classroom has been booed, it's their turn to pass the fun along. Each booing includes a ghost sign indicating the class has been booed. The sign gets posted outside the classroom to avoid duplicate booing.
