Have an indoor camp out celebration on the last day of school!
Tell your students to come to school in their pajamas and bring sleeping bags, pillows, flashlights, and their favorite books. Set up some tents (or make tents out of bed sheets and chairs) and make an indoor fireplace out of red, yellow, and orange tissue paper, rocks, and an electric candle!
Give your students a nice goodie box and have them reminisce their favorite memories from this school year. :)
