One slogan read, “Don’t blurt what might hurt.” Another said, “Have a heart, don’t take part.”

Such considerate catchphrases filled schools as part of programs held in recognition of National Bullying Prevention Month and Unity Day, which was Oct. 19.

In Seaford, middle school students wrote anti-bullying messages on sticky notes and placed them inside a huge heart hanging in the cafeteria next to the words, “United Against Bullying.” At Harbor Elementary School, students traced their hands on orange paper, cut them out and hung them in the hallways to create a long symbol of unity.

“This is the first Unity Day at the Harbor and everyone really came together to wear orange and support the movement,” Principal Thomas Burke said.

In Carle Place, 200 fifth- and sixth-graders at Rushmore Avenue Elementary School attended an anti-bullying workshop hosted by four teenage youth ambassadors with the Tourette Association of America. The ambassadors, in an effort to combat myths about the neurological disorder, shared their experiences.

In Franklin Square, John Street Elementary School held an anti-bullying week with a theme for each day — such as “Put Bullying to Bed,” with children wearing pajamas to school.

In Glen Head, kids at North Shore Middle School sat at lunch tables according to their birthday months to make new friends during a “Mix It Up Day.”

“Our students had the opportunity . . . to expand their social networks and move beyond established cliques,” North Shore counselor Flavia Finning said.
