My son just turned 6 in December, and is currently in Kindergarten. According to his Teacher he his having behavior problems at school. She is constantly sending notes home telling of his actions at school that day. For example some of these notes are... Today in class he tossed his coloring box in the air, but instead of catching it he dropped it onto the floor & it spilled everywhere; Today on the playgroung he kicked the rubber pieces & one hit a little girl on the leg; while coming in from lunch he slid on the rug in class like it was first base, today when asked by an adult to move down a seat at lunch he gave her a dirty look and put his head down on the table, when she asked him a second time he then moved but gave her a disrespectful look, a reffeal will be written. My question is just are these normal behaviors for a 6 year old kindergarten boy or should he already be completely aware of what to do in these situation? What is developmentally normal behavior wise at this age?
