The 100th day of school in Kindergarten is a big milestone, and it’s one of my favorite days of the school year! This special day offers a great opportunity to integrate fun, hands-on activities that engage kindergarten students and first graders alike. From literacy centers to math manipulatives, we explored creative ways to make this magical day a memorable experience. Here’s a blog post full of 100th day of school ideas to inspire your next classroom celebration!
Welcoming 100 Days of Smarts
To start our 100th day of school celebration, my kindergarten classroom featured a colorful banner declaring my young learners “100 Days Smarter.” This simple way to greet students set the tone for the entire day. By the end of the day, only one streamer was removed—proof that the kids had so much fun. This is definitely a great idea for a future classroom reward!
100th Day Reading Group
For our literacy centers, we read Rocket’s 100th Day of School, a little book that my students adored. It’s tough finding 100th day readers that cater to kindergarten students, but this one was a hit.
Using affiliate links, I purchased enough copies for small groups, ensuring a memorable experience. We also read 100th Day Worries, another favorite book that ties perfectly into the theme.
100s Chart Puzzles for Number Sense
Math activities were a big part of our day. One of the highlights was working with hundreds chart puzzles. I printed colorful charts and cut one set into pieces for students to reassemble.
These 100th day challenges supported critical thinking, number identification, and one-to-one correspondence. Adding a twist, students used a mystery picture format to reveal hidden images—a fun idea that kept them engaged.
Counting Sets with Fruit Loops and Paint
Counting to 100 is more exciting with hands-on activities. We used Fruit Loops to create 100th day trail mix and painted colorful dots with Q-tips to build fine motor skills.
To keep the activity stress-free, I offered differentiated versions of the mats, ensuring that all students could participate. Pairing chocolate chips, teddy grahams, and pieces of candy made for a fun day filled with math skills and smiles.
Writing: 100 Wants and Don’ts
This year, I shifted from traditional prompts like “100 years old” to a writing activity focused on what students would and wouldn’t want 100 of. Using word walls, students brainstormed creative answers, such as wanting 100 pieces of candy but not 100 mice. This was a great way to develop critical thinking and expand vocabulary. Pictures of your students writing these prompts make a great addition to your 100th day of school activities in fun ways. And yes you can use these in first grade as well as Kindergarten.
Skip Counting and Place Value Fun
Skip counting by 5s and 10s was a highlight of our math activities. Students colored a 100th day of school hat while skip counting their way to 100. Place value games using number cards and number lines helped reinforce tens and ones. These 100th day challenges were interactive activities that provided a great alternative to worksheets.
100th Day Crafts and Classroom Fun
Our 100th day hats and pattern blocks station were a hit. Students also used plastic cups and solo cups to build towers, combining fine motor skills with math manipulatives. For a fun twist, we used an aging booth app to show students how they might look at 100 years old. The laughter from this activity added so much fun to the day.
Memorable Moments with Small Items
The special occasion wouldn’t be complete without counting small items. From pom poms to paper plates covered in 100 Hershey Kisses, students explored different ways to represent the biggest number they’ve learned so far. These activities made the 100th day of kindergarten a magical day for all.
Wrap-Up and Resources
The 100th day of school celebration is one of my favorite days of kindergarten and 1st grade. It’s a perfect opportunity to combine hands-on activities, lesson plans, and free 100th day activities into a day filled with learning and laughter. Whether you’re planning for next year or looking for 100th day activity ideas, these interactive activities will make your big day unforgettable.

Color the Path to Skip Count
Another one of our learning activities today was focusing on skip counting by 5s and 10s. Students took these printables and colored their path while they skip-counted their way to 100.
Since one of our Kindergarten standards includes counting to 100 by 10s, what a great way to add standard-based fun. The count by 5s is a skill I teach, although it isn’t required. Going a little above with number sense never hurts.
(My little learners know how to skip count by 5s because of this game called SMASH you can read all about here.)
