Last Friday marked our final day of the school year, and we wrapped it up with an exciting Field Day celebration! Students enjoyed kickball, bouncy houses, face painting, balloon animals, and a cookout while spending time with their classmates and teachers one last time before summer break. It was a great way to celebrate all of the hard work, growth, and memories made throughout the year. We hope everyone has a safe and fun summer! ☀️🎉 Concept Schools
