100 Days Smarter: 20 Ideas to Celebrate the 100th Day of School in Your Elementary Classroom

The 100th day of school is an exciting milestone to reach in every elementary classroom. It signifies that the halfway point of the year has been passed, spring is around the corner, and the finish line is coming into sight. But more importantly, it presents a special opportunity to help students reflect upon the hard work they’ve completed so far, and celebrate the progress they’ve made. After all, you’ve packed a lot of amazing learning into those first 100 days!

So, make the 100th day of school a true event in your classroom! We’ve put together 20 of our favorite activities across all subject areas (plus some just-for-fun additions) to help you and your students enjoy this special day!

Math

Developing basic numeracy skills is a critical component of math instruction in the early elementary years. With that in mind, it’s easy to see how the 100th day of class is a great opportunity to challenge your students to what they’ve learned to use in fun and exciting ways. Here are just a few examples:

  • Sing, move, dance, and count your way to 100 with these 6 YouTube videos.
  • Create a 100 days of school crown with your students using stickers and stamps to count to 100.
  • Let your students design their very own 100 days of school T-shirt to showcase on this special day. (Extra points if you participate too!)
  • Get parents in on the fun with a 100th day of school collection activity! Simply have students collect 100 of a specific item at home (pennies, Legos, marbles, and small candies are all good options) and display them creatively. Here’s a parent letter and rubric for inspiration!

Reading

Lots of children’s literature authors have also gotten on board to help celebrate the 100th day of school. Here’s several of the best read-aloud selections we’ve found to incorporate in your celebrations:

  • 100th Day Worries: This is a perfect option if you’re looking for a read-aloud to go with a collection project like the one introduced above. In 100th Day Worries, join Jessica as she contemplates different collection ideas, worrying about which is the right one to show her class.
  • I’ll Teach My Dog 100 Words: As a class read aloud, the fun and clever cadence of this book makes it enjoyable for all. Try leaving this book out in a separate center and give students a chance to count 100 words (without counting ‘a’ more than once) and see if they can come up with 100 on their own!
  • 100 Snowmen: This seasonal read uses cumulative addition to count snowmen 1 to 100. Older children will enjoy the math problems included on each page, while younger students can practice counting the snowmen throughout their winter adventures in this tale.
  • One Hundred Hungry Ants: Join 100 ants as they march off to a picnic and discuss different ways to count to 100 as you go. A great cross-curricular read, this book illustrates math concepts such as division and multiplication in a way that is accessible for even your youngest students.
  • Miss Bindergarten Celebrates the 100th Day: Who doesn’t love Miss Bindergarten and all her Kindergarten adventures? In this story, join her as she celebrates 100 days of school with her class. 

Writing

The opportunities that this day presents to test your students’ writing skills haven’t gone unnoticed either. Here’s a few fun creative writing prompts that are appropriate for elementary students of all ages:

  • 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...”
  • 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!

Science

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:

  • Make 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.
  • Get out the Legos. Take advantage of these versatile toys for a fun engineering challenge. Have your students select 100 Legos (divide them into groups if you don’t have enough for each student) then have them each build a unique structure within a certain period of time. Give students the chance to show off their creations at the end!
  • Create Card Houses. The 100th day of school offers a perfect opportunity to present students with the classic task of building a house of cards. Divide students into small groups, give each group 100 playing cards, and see which team can create the card house capable of bearing the most weigh.

Just for Fun

Of course, the 100th day of school isn’t only about putting skills into practice—it’s also about having fun and building your classroom community! Try incorporating a few of these activities and special surprises into your agenda to round out the celebration:
