Today was probably one of the toughest days I've had all year. This group of 2nd graders as a whole is really difficult. They had a tough time splitting them up for this year, because there are so many behavior problems. I honestly have the best of the four classes overall. Prior to winter break, they were fairly well-behaved. I only had to contact parents a handful of times for behavior concerns. Some of the kids that I was warned were the toughest were actually behaving pretty well. Since returning from break on January 5th, however, everything has gone downhill. I don't know if it's cabin fever, the kids getting too comfortable, or what, but they have been just awful. I have written more majors and minors (our PBIS write-ups) in the past 4 weeks than I have in the first 4 months of school combined. Today I had one student steal property from another, and then lie about it. Another student, who is usually very well-behaved, kicked and punched someone at recess (playfully, but still). One girl, who is the most soft-spoken, sweetest little girl you'll ever meet, wrote an opinion piece about how much she hated another student in our class, and then lied and said someone else put it in her writing binder. I am getting so frustrated. I spent the entire month of January reviewing expectations, and working on transitions. For the past few weeks I have been giving little or no warnings, since they know the expectations. They receive a consequence, and I notify parents of the behavior. Many kids cry and seem visibly upset with getting in trouble, but they don't change. I guess I'm not really looking for answers, but has anyone else experienced this before? I'm honestly just shocked, because this is the time of year when things usually begin to fall into place, and my students are on their best behavior. I've never had a class that started out strong, and went crazy in January.
