100th Day of School — It’s about Learning (2024)

The 100th day of school is a special milestone celebrated in many educational institutions around the world. It is particularly popular in elementary schools, often filled with fun and educational activities centered around the number 100.

How to celebrate

Here are activities I like that blend learning into the celebration of the 100th Day of School:


As a class, come up with two locations in each state, to total 100. One will be oriented around geography and one around history (such as “Kansas became a state January 29, 1861”). Include a brief description and a picture and then share the collection with parents and schoolmates in the class newsletter or another vehicle.


Research what happened the hundredth year of your home country’s existence. What was the country like a hundred years ago? What caused it to change? Who was president? What has been invented since then? Divide the class into groups so the project can be completed in one class period. Then, have everyone copy their information to a digital magazine (like you can create in Canva or Adobe) and share it with everyone.


Read Rosemary Well’s acclaimed book, Emily’s First 100 Days of School about the daily achievements of grade schoolers for their first 100 days. It’s 54 pages and perfect for ages Pre-K-2. You might plan to finish it by the 100th day and compare the character’s accomplishments to the class’s.

Another way to tie this celebration into literacy is to curate a list of one hundred favorite books students have read. This might become the core of an end-of-school (or back-to-school) Wish List for your class library. Have each student write a brief description of the book(s) they suggested (no more than one hundred words). The completed list can be shared using a simple Word or Google Doc or more professionally with a classBiblionasium or Goodreads account.


From the very first day of school, have your students track the number of days they’ve been in school in anticipation of the 100th day, marking the days in ten bundles, paving the way to counting by tens and ones.

Students can engage in various counting exercises related to the number 100. This could include counting 100 objects, creating art projects with 100 items, or writing 100 words.

Have students work in groups to come up with one hundred ways to represent the number “100”. Some examples are:

  • 50+50
  • 102-2
  • 400/4
  • 5*20
  • 4(20+5)
  • the square root of 100 + 90

Teachers may design math challenges and games that involve the number 100 to reinforce mathematical concepts in a fun and interactive way.


Physical activities during winter often become calisthenics or personal fitness, exercises that can be done indoors or in the gym. Have students do ten sets of ten different exercises (i.e., jumping jacks, sit-ups, and deep knee bends) to learn the concept that 10 sets of 10 equal100.

Another indoor physical activity is walking 100 steps and measuring where you end up.

Organizing physical activities related to the number 100, such as 100 jumping jacks, 100-second challenges, or 100 steps around the school, adds a healthy and active component to the celebration.

Personal interactions

Have students get one hundred friends, friends-of-friends, and/or family to answer one hundred questions revolving around the class curriculum (say, “Who was the 10th President?). They can start asking at the beginning of the school year but must submit their answers on the 100th day. Decide what the winner gets.

Students calculate when members of their family will turn 100, starting with themselves. You might add a touch of history by finding out what historic event shares the day with the family member’s one-hundredth birthday. Use a website such as “This Day in History” to help.


For older students, create a blank Periodic Table in Google Sheets, Padlet, or any other webtool that allows multiple people to write at once. Break the class into teams and assign each an equal number of the elements up to one hundred. Teams will fill in the symbol of the element onto the correct position on the Periodic Chart.


Make a list of 100 new words learned this school year and their meanings. You might have been organized enough to collect these since the school year started or you might have students do this from memory. If you use word lists, don’t let them peak! When you have the list, add all words to a word cloudand share this “100 New Words Learned This School Year” with parents and classmates through the class website, blog, or LMS.

Another fun idea is to have students see how many words (or phrases) they can make with the two words “one hundred”.


Write a 100-word story. It must include characters, setting, plot, rising action, climax, and whatever else is required of students at their grade level. When students finish, publish them to a Hundred Days ebook using Adobe Spark or similar and share it with classmates and parents.

Another fun activity is to ask students to write about how they spent the last 100 hours using only 100 words. If they don’t want to write, they can record it as an audio or video file but it still must be 100 words. A fun option is to create a Flipgrid where students enter their recorded response in the visual grids and then all responses are shared with classmates, parents, or anyone with access to the Flipgrid.


Here are a few more:

  1. Dress-up Day: Students and teachers often participate in a “Dress-up as 100 Years Old” day, where they come to school dressed as if they were a centenarian, complete with gray wigs, canes, and wrinkles.
  2. 100th Day Collections: Students may be encouraged to bring in collections of 100 items, fostering creativity and organizational skills.
  3. Themed Lessons: Teachers may incorporate the number 100 into various lessons across different subjects, making learning engaging and relevant to the milestone.
  4. 100 Days Smarter: The day is often framed as a celebration of the progress students have made in the first 100 days of school, emphasizing the growth and learning that has taken place.
