Senior students from “House Sugar Grove” spray-paint their house animal, a shark, during the spray-paint contest at Delaware Hayes High School Friday morning. Students had an hour to spray-paint artwork with the theme of “house pride.” School officials said it was the last day for seniors and there were dozens of house activities and contests throughout the day. Hayes’ student body was divided into eight houses at the start of the school year in an effort to foster more relationships and involvement in school activities.
