Where Did the 100th Day of School Come From?

First up, a little history lesson. Although there are disagreements about the exact origins of the 100th Day of School, there are two leading theories about where it came from:

1. One popular theory is that a teacher named Lynn Taylor introduced the celebration for kindergarten in the 1981-82 Newsletter of the Center for Innovation in Education. Taylor is said to have been inspired by Sesame Street, in particular a magic trick performed by Count Von Count, who turned 100 pennies into a dollar as part of a magic trick.
2. The 100th Day of School may also have originated with Mary Baratta-Lorton, a California teacher whose books about teaching primary-grade math had a major impact on how kids learned mathematics in the 1970s and '80s.

Which Two Months Will the 100th Day of School Usually Fall In?

Life would be so much easier if we could just look up the 100th Day of School 2024 on the calendar, but the wide difference in school start dates across the country plus the varied school holidays means this day is rarely the same from district to district!

All that said, if you're planning ahead, you can probably count on a January or February celebration as it's a little more than halfway through the school year in most parts of the country.

How Do You Celebrate the 100th Day of School?

Ah yes, the big question! How you celebrate the 100th Day of School is all about the level of creativity you have — and let's face it, the time you have to commit to the experience.

Hit by a ton of snow days in January? You may not be able to spend too much of your instruction time on 100th Day activities.

Then again, if it's been a long winter already, allowing your kiddos to dress up as 100-year-olds may just be the sort of morale booster your class (and the teaching staff) needs!

We came up with a variety of 100th Day of School activities that can work for big 100th day celebrations, plus some smaller ways to mark this momentous day in the school calendar. Explore the collection for simple printables and bigger projects — there are options for every kind of teacher and every kind of classroom!
