    Blue & White Day

    This will be a dress down day. Every AC student in grades 1-12 will be assigned to the Blue Team or the White Team and should dress in their team color that day. (Team color assignments will be shared with families closer to Homecoming Weekend.) Students in grades 1-12 will then enjoy a fun-filled field day, and our Little School, AC3s, Pre-Kindergarten, and Kindergarten students will come out and cheer on both the blue and white teams! Please be sure students wear sneakers on this day.
