100 Days Smarter: Celebrating the 100th Day of School

100 Days Smarter: Celebrating the 100th Day of School

The 100th day of school is an exciting time in the elementary classroom! Quite literally, this day signifies the 100th day of class in the school year. The symbolic representation, however, is much greater than that. The 100th day marks a special opportunity to reflect upon and celebrate major milestones in your students’ academic achievement.

For this reason, we want to help you recognize this landmark day in the school year. And, the best part is celebrating this day can span all subjects! Take a look at a few activities, classroom projects, and even snacks for your students to enjoy throughout this special day.


In the elementary years, developing basic numeracy skills is a critical component of math instruction. With that in mind, it’s easy to see how the 100th day of class is a great opportunity to test those skills in fun and exciting ways. Here are just a few examples:

English Language Arts

Many children’s literature authors have also gotten on board to help celebrate 100 days of school. Incorporate reading and language arts activities that center on this all-important number with these ideas:

  • Read, write, and sort 100 words! Students can play independently to test their skills or pair up to compete against a partner, drawing words and using them in a sentence.
  • Incorporate a “100 days”–themed book into your daily read-aloud time to practice comprehension skills while counting to 100. Check out these recommended book lists from and This Reading Mama for a few ideas.
  • Incorporate a poetry lesson with this short 100th day poem. Spoiler alert: it’s not just about the 100th day of school—it also has exactly 100 letters!


The opportunities that this day presents to test your students’ writing skills haven’t gone unnoticed either. Creative writing prompts are available for elementary students of all ages. Try out a few of these activities with your students:

  • Even your youngest learners can write their favorite sight words. Capture them on a class anchor chart with the following theme: “We can write 100 words!”
  • Use a fun aging app to capture your students at 100, and then challenge them to write on the topic: “If I were 100 years old…”
  • Try out a writing prompt that will excite your students (and promises to give you a little chuckle) by asking your learners to finish the sentence: “If I had $100 dollars...”


There are tons of fun STEM challenges that inspire critical thinking for your youngest learners. Incorporate 100 items, and suddenly, you have an awesome task that also fits the theme of the day! Check out these great examples:

  • Build a clothespin fort. This simple engineering exercise asks students to find a way to fit 100 clothespins around the four sides of a box. Watch as your learners are forced to get creative when they quickly run out of room along the box’s perimeter.
  • Build a cup tower. Keep things interesting by tasking your students with building the tallest tower, or make it a speed challenge by timing your learners. See if anyone successfully uses 100 cups.

Classroom Culture

This day isn’t just about putting skills into practice—it also presents an opportunity to build your classroom community. Celebrate your students’ accomplishments with activities and a few special surprises like these:
