What Is the ‘100th Day of School’?

The ‘100th Day of School’ is a celebration that usually takes place sometime during the month of February. It all began back in 1979 when teacher Lynn Taylor and her fellow teachers got together to celebrate the 100th day of school. She published the idea two years later, and since then, classrooms have been celebrating this important milestone every year.

We’ve gathered a list of 27 of our favorite 100th day of school costumes, crafts, and activities to help both kids and teachers celebrate at school.
