My favorite 100 Days of Kindergarten project has been a winner year after year. It's a tough call, honestly, because there are SO many fun 100th-day activities for kindergarten! I'll just go on and let the cat out of the bag here and now. Our kindergarten 100th day shirts are THE BEST THING EVER on that oh, so special day!

Not to worry, I'm going to share a SLEW of 100th-day shirt ideas with you, as well as what works in my kindergarten classroom – I'm on year 12 ~ an will only give you the things that my kids have LOVED.

Do you teach kindergarten? Then…you likely know this look. It's the look of someone who is overwhelmed, getting everything in order for the big 100th day of kindergarten.
That was me for years. Not anymore.
I got you, boo.

I've spent every year with my team trying to wrangle up what we've used in the past, creating a hodgepodge of fun for the 100th day. Some things work, and some things don't. But this pack of goodies I've created for you is my spin on the things we love the most.

ALL IN ONE PLACE.

100 Days of Kindergarten project

I've taught kindergarten for 10 years. For the first 3 years I taught, the teachers and the kids all dressed up like we were 100 years old. Walkers, canes, wigs with rollers…the whole 9 yards! It was a sight to behold, FOR SURE, and most of us enjoyed it.

However, I experienced a few unexpected things:

  • A few kids were actually really scared of me and my team, all dressed up and cackling like crazy as we held walker races down the hall. 😉 I tried to explain it was just for fun, but they weren't having it.
  • I also experienced quite a few kids who did NOT enjoy dressing up and getting wrinkles on their faces – it sort of freaked them out a bit.
  • And then you had those who just didn't want to dress up, or their parents didn't want to mess with creating a ‘look.' Totally respect that.

On the flip side, I had kids who LOVED dressing up and insisted on walking with a cane at turtle speed – EVERYWHERE. WE. Weeeeeennnnnnnnt.

The final straw for me was watching the canes become swords. When one five-year-old's bald wig was knocked off, and another's dentures flew out (ok – I think I may have dreamed that part!), I decided to bring another idea to the table.

We are getting ready to start our 9th year with this alternative 100 Day Kindergarten Project, and we have received RAVE reviews from kids, parents, and even the staff at our school, who LOVE seeing all the creativity year after year.

This 100 days of kindergarten project is SUPER simple to set up. We send the parents a letter home about 2-3 weeks before the big day, full of helpful hints! This letter should pretty much fill YOU in on how it works, too – it's THAT easy. Click here to learn more!

We also have a FASHION SHOW on the 100th day. This is nothing fancy, just a low-key moment in our classroom together. I have them sit in two rows on either side of our carpet, creating a RUNWAY down the middle. I'll call each name, and then as they strut their stuff down the catwalk – I'll read from the half-sheet of paper they have filled out and returned from home. BONUS: Play some tunes! (I've got a great playlist for you, too!)

In addition to the epic 100 Day Kindergarten Project, I'm going to briefly share 10 more AWESOME ideas that I've found the kids really enjoy on the 100th day.

Here's my advice…do NOT get overwhelmed. You'll be spending some prep time at the copier for SURE…but it will be worth it.

Scroll through these 10 ideas, click on any that peak your interest, and if you can't decide – no worries! I have them all wrapped up neatly in a bundle for almost 1/2 off!

Ok, kindergarten 100th day crowns are a MUST. Period. All you have to do is print on paper or cardstock, glue onto a sentence strip, and then fit it to their head and staple. (Well…don't staple TO their head. Staple the sentence strip.)

2. 100th Day Glasses

These 100th day glasses are always a fun addition. Just use popsicle sticks, a little hot glue, and they have a fun photo prop! (That they carry around for weeks after…just sayin'…)

3. 100th Day Necklace (Fruit Loop-Style)

Another tried and true favorite. BUT…I have some special tips and tricks for you with this sorting mat and my “tens tags”! (Lesson learned the hard way!)

4. 100 Days Brighter Bookmark

You could print these in color, or on white cardstock and let them color. Hole punch the top and add some ribbon for some flair! I'm considering printing the color ones beforehand, laminating, adding a ribbon, and using them as a little extra take-home treat.

5. 100 Days Brighter Certificates

These certificates are editable! You could also print and write in the info…your call!

6. 100th Day Snack – Trail Mix Sorting Mat

7. 100th Day Snack Trail Mix Bag Topper

This one is super fun and they love it. I do prep these before hand – using a wafer cookie or Keebler Vienna Finger Cookie for the 1, and Keebler Fudge Striped cookies for the 0s.

9. 100th Day of School Writing Prompt Craft

This is something we do the week leading up to the 100th day. Some are ready to sound out and write the answers on their own, but others just tell me their answers and I write them in. I display them on our door – and it just adds to the party-vibe!

10. 100th Day of School BUNDLE

Ok…this one has it ALL. The bells. The whistles. The flair. The whoopdeedoo.

Again…you have EVERYTHING you need in ONE place. And you get it all for almost 1/2 off. What if you don't want to use EVERYthing? No problem. You'll always get any additions at no cost – so it's a steal.

OH. AND THERE ARE BONUSES THAT ONLY COME WITH THE BUNDLE! Juusssss sayin'. These bonuses are what I have on their tables as they come in, they are what my fast finishers use, they are my saving grace if something falls off of a 100-day shirt and there's a hot-glue gun emergency…

100th day read aloud for kindergarten

I'll leave you with a few extra thoughts…

In recent years there have been more and more 100th day books for kindergarten, and some of them are pretty good! I do have two favorites that I stick with: “Miss Bindergarten Celebrates the 100th Day” by Joseph Slate, and “100th Day Worries” by Margery Cuyler.

I like to read the “100th Day Worries” a day or two before our celebration, and give them a challenge to try to find 100 ‘somethings' at home that they could bring in to share. Not everyone takes the challenge – which is of course, fine. But the ones that do are usually pretty creative. You can find both of these books here.

Where do I get all the things like sentence strips, etc?

I have all of my favorite 100th day sentence strips, Astro Bright paper, etc. in my Amazon storefront, take a look and see what might need to grab!

And that just about sums it up! We have approximately 9 days to go until our 2026 celebration, and my kids are practically buzzing with excitement. I hope that the one-stop-shopping bundle of all the 100 day ideas kindergarten style will help streamline things for you.

And if you decide to go for the 100 days of kindergarten project t-shirt idea – I'd LOVE to see what your kids come up with!

Parents – if you have an amazing idea – please drop it in the comments below! Happy 100th day my friends!

100 days smarter sign in kindergartenI've used this same sign for AT LEAST 6 years. Walgreens posterboard.

I made this little sign and hang it inside our door frame every year. I grab a chair, have them stand on it, put their hands up in the air, and snap a pic. It's PRECIOUS. Then, I have them all gather at the doorway; I stand in the chair in the hall, look down on them, get the sign, and have all of them put their hands up in their kindergarten 100th-day shirts. EASY.

The little tassels? They actually came off of the ‘JUST MARRIED' getaway truck from my 2016 wedding! Repurpose people. Store things well. They will last.

OH. And once there was COVID.

Remember that? YYyeeeeahhhhh. OUCH. We had to figure out a way to make our 100th day of school a success THROUGH THE SCREEN. To five-year-olds.

AND…..WE DID.

One thing to keep in mind…this day is MAGICAL for kindergarteners. No matter what…they will be happy if YOU deliver YOUR excitement. Buckle up. Have fun.
