Celebrating 100 days of school has turned into a big event in classrooms across the world! And… why not? Marking the 100th Day of School provides a great way for elementary teachers to celebrate a variety of mathematical concepts using the number 100 and to add a bit more fun to what can be a rather dreary part of the year in many parts of the country.
Looking for some new 100th day ideas for 2023? We can’t tell you the exact date of the 100th day of school — it may vary from school to school depending on when your school year started, how long your school breaks have been, and if you have had any snow days — but we can some creative ideas from the teacher team behind all the resources on Teach Starter!
100th Day of School Ideas
Once the winter break is over, the 100th Day of School can sneak up on you quickly. Usually popping up on the school calendar in January or February, it arrives just as you’re looking at meaningful ways to honor Dr. Martin Luther King Jr., prepping for Groundhog Day, and of course planning for Black History Month. Oh, and don’t forget Valentine’s Day and Presidents’ Day. Needless to say, we understand why you might be feeling frazzled and out of ideas to celebrate being in school for 20 weeks (aka 100 whole days).
That’s why we’ve put together a few favorites to inspire you!
As an added bonus, just click on the little blue links on any of the ideas below to grab some printables to save you time on lesson planning!
100th Day Snap Cube Challenge
We love having kids make 10 with snap cubes and plenty more, so why not pull these manipulatives for a 100th Day challenge? Provide students with 100 cubes, and challenge them to see what they can build?
Take 100 Steps Around the Classroom
Need a mid-morning or mid-afternoon brain break? If it’s the 100th Day of School, that definitely means taking 100 steps around the classroom, and seeing where each child ends up, doesn’t it? Before breaking, students can make predictions about how far from their desk or chair they might get with 100 steps!
Grab our free 100th Day of School Snack Ten Frames, and have your students practice counting by 2’s or 5’s with some tasty treats like popcorn.
Create a “100 Of” Anchor Chart
What would your students want 100 of? Cats? Footballs? Create an anchor chart with your students listing all the things they’d like to have in serious bulk! Alternatively, you can create an anchor chart with your class showing off 100 words they now know how to spell!
Skip Count to 100 on a 100s Chart
Honor the origins of the 100th Day of School with a skip-counting activity on a hundreds chart! We had a little too much fun making 100 balls of playdough for our playdough-themed 100s chart, but you can also have your students count out 100 pieces of candy on a 100s chart like this fun candy-themed chart.
100 Days of School Tracker Classroom Poster
When you’re nearing the 100th Day of School on the calendar, a quick activity that will take almost no time out of the school day is tracking the number of days that have passed and calculating how many days are left until you hit 100.
You can download our printable 100 Days of School Tracker poster and include it in your morning routine, or use popsicle sticks to keep track of the days and teach students about bundling the sticks together once they get to ten. This is a fantastic way to introduce the concept of place value to your students.

100th Day of School Certificates or Badges
Providing your students with a 100 days of school certificate can offer each child a sense of accomplishment, and it gives them a “prize” to take home to show off to a parent or guardian.
Alternatively, you can provide a 100th day of school badge to each of your students. Use a safety pin or, better yet, copy these templates on sticker paper so that no safety pins are needed! Stick one to each child’s shirt.
Dress Up as a 100-Year-Old
This is an idea that may have been around for a while now, but it never gets old for the kids who get to have a little fun dressing up the way they imagine a 100-year-old would. You can also ask the principal if they’ll dress up like a geriatric person to make a visit that will leave your kiddos giggling all day long.
100 Days of School Mini Activity Booklet
The 100 Days of School Mini Activity Book template makes a fun booklet of activities for students to complete on their 100th day of school.
Activities in the booklet include:
- Students finding the number 100 in a group of numbers.
- Students creating their very own wacky creature.
- Students completing 100 different workouts.
- Students completing the sentence: “If I had 100 legs I would…”

100 Days of School Writing Activity
Incorporate the 100th Day of School into a writing activity — offering a prompt to show off how much students have progressed in their first 100 days of school.
With the 100 Days writing template, students complete the sentence ‘I’m 100 days brighter because…’ They can then decorate the child’s head and hands and attach them to the writing template to be displayed in the classroom.
