Making the 100th Day of School Memorable
Before we dive in, let’s zoom out and think big-picture for a minute. What do YOU want your 100th Day of School Celebration to feel like? Here's my thoughts. . . The 100th Day shouldn’t just be busy work. It’s an incredible opportunity to celebrate progress, build classroom community, and help students see how much they’ve grown since day one.
This is why I always looked for hands-on, exciting, and unique ways to celebrate. It should feel like something out of the norm, because it is! The 100th Day of School only comes once per year, and I wanted my kids to feel the excitement!

- This activity takes about 10-15 minutes to prep and can easily be set up before you leave for the day, or first thing in the morning.
- I recommend using bright and fun colors for impact.
- Take a photo of each child as they step through the zeros and save for memory books.
2. Friendship Trail Mix
This activity is included in my 100th Day of School Activity Pack. Here's how it works: Send home a Ziplock bag before Day 100 and ask families to count 100 small treats (Goldfish crackers, pretzels, cereal, marshmallows, etc.). On Day 100, combine everything for a giant Friendship Trail Mix!
Teacher Tips:
- This one is super simple to prep, just print the notes from the packet and send them home! It takes less than 5 minutes.
- Make sure to bring extra snacks and Ziplock bags for students who forget or are unable to contribute.
- This activity is perfect for morning work or snack time!
3. Dress Up Like You’re 100 Years Old
Teacher Tips:
- Send home reminders well in advance. Do a quick email blast the day before as a reminder, too!

- Make sure to take a class photo and get a copy printed for each child. I liked to add these to memory books!
4. The 100 Cup Challenge

- Set a timer on the interactive whiteboard so students can see how much time is left.
- Make time to do this a few times and award small prizes like stickers for each group that wins. It's a hit!
5. Make “100-Year-Old You” Photos with an Aging App
Teacher Tips:
- Take photos before the 100th Day and don't show the kids.
- Print them out and set up a secret bulletin board called "When We're 100!"
- On the day of the event, unveil your bulletin board and let the kids have a look. Send these home for parents to see, too!
6. 100th Day Grocery Bag Vests
Teacher Tips:
- This activity takes about 20-30 minutes total and requires minimal prep. You can cut the vests ahead of time, or have a parent helper do this to save time.

- Once they are dry, have kids put them on and walk through the hallways for a 100th Day Parade!
7. How Many Licks to Get to the Center?
Teacher Tips:
- Expect total silence... kids get super focused with this one!
- Remind the kiddos not to bite the lollipop.
- Set aside time to compare charts after the activity.
8. Hershey Kiss Hunt (1-100)
Teacher Tips:
- This is the perfect after recess activity because it gives you time to "hide" the kisses.
- Explain the rules of how it works BEFORE kids enter the room and have them quietly "hunt for kisses" and add them to the chart.
- You can play some fun sleuthing music like this to dial up the excitement!
9. Write 100 Teeny Tiny Sight Words

- After making their tally marks, students can decorate their crowns with markers and stickers.
- This is perfect for a 100th Day of School photo!
12. Fruit Loop Necklace - Count by 10's
Teacher Tips:
- Prepare the strings ahead of time by cutting them to size. Be sure to use lacing string!
- When you're ready to have students start stringing, tape them to the counting mats to make them more manageable.
- This is the perfect math or fine motor station if you plan to do rotations!
13. Flip a Coin 100 Times
