With more than half of the school year under their belts, students and teachers at Seven Oaks Elementary School celebrated their 100th day of classes on Friday.

Kindergartners and first-graders created projects using 100 items, enjoyed special snacks and imagined what life would be like when they are 100 years old, according to school secretary Debbie Leimbach.

The milestone came with one more surprise—several of the teachers dressed up as 100-year-old versions of themselves.

Leimbach even submitted a photo to Patch to prove it.
