Happy Thanksgiving, Three Village!

Group Picture of Students thumbnail252319
Students across the Three Village Central School District celebrated Thanksgiving and its many traditions ahead of the holiday. They learned about the importance of giving and took part in service projects to help the greater community.

The student council at Nassakeag Elementary School collected candy from staff and students after Halloween. Members decorated brown paper bags with Thanksgiving artwork and filled them with candy to be donated to Our Daily Bread Soup Kitchen and Food Pantry at St. James Roman Catholic Church. The bags were distributed during a Thanksgiving meal held at the church.

Third graders in Mrs. Frole’s class at Minnesauke Elementary School collected food items and gift cards to create Thanksgiving meal baskets for local families in need. Students donated, designed and wrapped each basket. They also created Thanksgiving cards to be given to local veterans with their holiday meals.

At W.S. Mount Elementary School, Mrs. Costanza, Mrs. Mazzarone, and Mrs. Pushee's classes joined together to host a food drive. They assembled four gift baskets for local families to enjoy this Thanksgiving. In addition to this service project at Mount, the building hosted a schoolwide Thanksgiving parade and Pre-K classes enjoyed a Thanksgiving feast with their families.

The Three Village Central School District honored Veterans Day with several in-class lessons and events. Students of all grade levels at Arrowhead Elementary School designed cards and wrote messages of thanks to be donated to the Northport VA. Additionally, the Arrowhead school community participated in a Jeans for Troops Day on Thursday, Nov. 9. They collected monetary donations for the GI GO Fund which helps veterans returning to civilian life.

Similarly, the W.S. Mount Elementary School student government sponsored “Red, White and Jeans,” raising $330 to benefit military veterans and their families. Students and staff donated one dollar to wear jeans for the day. They also created cards, placemats and thank you notes to be delivered to the Stony Brook Veterans Home.

Halloween spirit was seen across Three Village on Oct. 31. Students at the elementary schools paraded outside their buildings to show off their costumes to families and friends. Celebrations took place in the classroom too, with students decorating pumpkins and participating in Halloween-themed lessons.

Ward Melville High School held its annual Trick or Treat Street to provide a safe, fun environment for families to go trick-or-treating. High School clubs decorated doorways on the exterior of the building and handed out candy. Many of the stations had activities for children to participate in including coloring, pumpkin picking and a bean bag toss.

Islanders Day at Mount

Students at W.S. Mount Elementary School in Three Village were excited to welcome Sparky and members of the New York Islanders organization to the building on Oct. 25. Energy was high as students filled the auditorium for an interactive presentation about teamwork and healthy lifestyle choices.

Students “warmed-up” for the assembly with stretches led by Sparky, which was then followed by a quick game of trivia. Students answered questions about making healthy choices. A student and teacher were chosen from the crowd for a timed challenge where they had to dress in hockey goalie equipment. The student worked with a team and won, whereas the teacher worked alone – showing how far teamwork can take you.
