The 100th day of school is a huge deal in kindergarten! The students have worked hard to learn how to count to 100 and it is now time to celebrate! I have had the pleasure of throwing many 100th day of school celebrations over the years so I thought I would share some of my favorite ideas and treats.
Have a surprise waiting on their desks.
I love seeing my students’ faces when they walk in and see their desks decorated with confetti and a special treat and award waiting for them. Since it is early in the morning I like to use the mini-doughnut treat with a wafer cookie to represent the number 100. I place them in a Ziploc bag with a treat bag topper that says “Donut” you know it’s the 100th Day of School? You have learned a “hole” bunch!”. I also give them a special, personalized award as a keepsake to commemorate our special day.
In years past when I taught both morning and afternoon kindergarten, I would give my afternoon class these cookie treats since they arrived later in the day. I would place a wafer cookie along with 2 fudge stripe cookies in a baggie and attach a “Happy 100th Day! You’re a smart cookie!” treat bag topper. I would give them a different personalized keepsake award than the morning class to “change it up” a bit and make each class feel special.
Our 100th Day Mascot, Spot
Anyone who knows me knows I am a huge dog lover, soooooo I had to incorporate a dog into our celebration! Since I couldn’t bring my 2 adorable beagles in for the party (lol) I decided to have a spotted Dalmatian named Spot as our official 100th Day mascot. The students had to give Spot exactly 100 spots using either a bingo dabber or a Q-Tip dipped in paint.
I’m Celebrating 100 Days Crown Craft
It just wouldn’t be a celebration without crowns LOL! I used to purchase already-made crowns years ago but then I saw the idea of allowing students to decorate their own and I wanted to try it. Turns out that the students like decorating their own crowns much more than just putting on a crown that looks like everyone else’s because then they can have a personalized, unique looking one. I also like them better because they are very simple to make plus I don’t have to purchase new packs every year. I simply copy the crown template I created onto cardstock, have students color and/or write on it, and then attach and size the strip to fit their heads. They are so proud to show everyone that they are celebrating a super special day!
AgingBooth Writing Activity
A technology activity that I really enjoy doing is using the free AgingBooth app to create a “When I am 100 years old” writing activity. I make sure to get a picture of each student prior to the 100th day of school. I then use the free AgingBooth app to make students look older and save the pictures. I would advise you to do this step yourself instead of allowing the students to do it because the app has ads that come up that young students may click. Here is an example of a before and after. Students love seeing the older version of themselves!
I print out a template with students’ photos and then have them write and/or draw what they think they will be doing when they are 100 years old.
I have also had students upload their photos to Chatter Pix Kids and record what they think they will be doing when they are 100 years old. You can also use the Record Tool in Seesaw.
100 Chart Secret Picture (Number)
This is such a fun and cute way to practice number recognition! I call out the numbers in random order and the students have to find each number on their 100 charts and color them in. When finished, they realize that it creates the number 100 (well some youngsters figured it out before the end lol).
Roll Your Way to 100
This activity is a fun way to practice estimating, counting, adding, subitizing, and number recognition all rolled into one (sorry, couldn’t resist the pun). It can be done as a whole group, in pairs, or individually. To begin, students estimate how many rolls of the dice they think it will take to reach 100 and write it at the top of the page. Then they roll the dice and color in the correct number of squares on the 100 chart using a different color crayon each time. After they reach 100, they count the number of colored sections that represent each roll of the dice and write it on the top of the paper and compare their prediction with the actual results.
100 Chart Puzzles and 100 Piece Puzzles
Cut up a 100 chart into puzzle pieces and have students put it back together again for fun number sequencing practice. I also put out some of our favorite 100 piece puzzles for students to put together.
100th Day Seek and Find: Hidden Pictures Activity
Seek-and-find activities are always a hit with kindergarten students, and this one is a fun way to build focus while still working toward 100.
In this activity, students search for hidden pictures and work to find 100 objects total. To help with accuracy, I like to have students circle each type of object using a different color. This makes it much easier for them to go back and count how many of each object they found and double-check their totals.
It reinforces counting to 100 while building visual discrimination and attention to detail — skills that are so important at this age.
I Would Like 100…, I Would Not Like 100… Activity
Students use sentence starters to complete a writing and drawing activity about what they would like (and not like) to have 100 of, fostering creativity and reinforcing number sense.
I first write the sentence starters on the whiteboard and we brainstorm and discuss possible answers.
Then, students write or draw their own responses.
You can also incorporate some technology into this activity using the free app Pic Collage (we use the version called Pic Kids specially designed for younger children), Seesaw, or Google Slides.
I showed students the following sentence starters – I would like to have 100… , I would not like to have 100…. We discussed it as a group along with some possible answers then students made their own versions in Pic Kids. They typed in each sentence starter and then searched for pictures to complete each one. Since Pic Kids web search is safe, they could use it if they needed it.
100th Day of School Snack Ideas
I have been doing the trail mix snack idea for years and still love it. Each student is responsible for bring in exactly 100 pieces of their ingredient for our trail mix (M&Ms, Cheerios, mini-pretzels, Chex cereal, Goldfish crackers, mini-marshmallows, raisins, chocolate chips, popcorn). We combine them together to create a trail mix snack.
I have recently started adding this cute and healthy snack as well – a baby carrot and 2 cucumber slices to resemble the number 100. I make them either the night before or first thing in the morning and place them in snack bags with the topper “Hip Hip Hooray! It’s the 100th Day!”.
100-Second Challenges
These quick challenges keep students engaged while reinforcing counting, estimating, and problem-solving skills.
Before each challenge, students make a prediction about how many times they think they can complete the task in 100 seconds. Then, I set the timer and let them try it out. After time is up, students count their results and compare them to their prediction. Then, reflect on whether it was easy or hard.
Some favorite classroom-friendly challenges include:
- stacking Unifix cubes into one tall tower
- connecting linking cubes
- linking paper clips into a chain
- sorting counting bears by color
- transferring pom-poms into a cup
- writing or drawing as much as possible in 100 seconds
These challenges can be done:
- as whole-group activities,
- in small groups, or
- as center activities.
Can You Be Silent for 100 Seconds?
This is a fun challenge to do with students – see if they can be completely silent for 100 seconds! You can also pair it with the next activity by telling them if they are quiet for 100 seconds they will get a $100 bill LOL.
Personalized $100 Bills
Students love seeing their face on $100 bills! You can create these free at PhotoFunia.com (please note that you do NOT have to download anything – ignore the green download buttons – they are ads). Click the Choose Photo button, upload your photo, and click Go.
Which Container Has 100 Items?
Set out 3 containers with candy and only fill one of them with exactly 100 candies. Have students guess which container they think has exactly 100 candies in it. Record their guesses. After everyone has put in their guess, dump them out and count.
100th Day Science Experiment (Candy Melting Fun!)
If your students love hands-on science like mine, this is such a fun (and memorable!) way to tie science into your 100th Day celebration.
For this activity, students count out 100 candy-coated chocolates (M&Ms, Skittles, or jelly beans work great). Counting by tens makes this a perfect math warm-up before the experiment even begins. Using a counting mat makes it simple!
Once students have their 100 candies, they arrange them on a large white dish or pan to create a shape or design. Before adding water, students make a prediction about what they think will happen.
Next, I slowly pour very warm water down the side of the dish (this is a teacher job!), being careful not to move the candies. As the warm water touches the candy, the colored sugar coating begins to dissolve and the colors spread through the water, creating the prettiest patterns. The kids are always amazed!
This activity works really well as:
- a whole-group science demonstration, or
- a small-group investigation, where each group helps count and prepare part of the 100 candies before observing the results together.
Students then draw what they observed and talk about what happened, making this a meaningful way to combine math, science, prediction, and observation on the 100th Day of School.
100 Link Paper Chain
Before we create our paper chain, I have students estimate how long they think a 100 link paper chain will be. I take them out in the hallway and show them where we will place the beginning of it and then have them go stand where they feel the chain will end. I give them each a piece of masking tape to mark their spot and they write their names on it. Then, we split up into groups. Each group gets strips of paper with numbers on them and they must put them in order and link them together. Next, we come together as a class and link all of the group chains in order from 1-100, take it out into the hallway, lay it down and see if anyone’s guess was close to the actual length (I couldn’t get a picture of the entire chain – here is a section with some of the students’ guesses beside it).
100th Day of School Take-Home Treats
I also like to give students a little something special to take home to commemorate our special celebration. Here are some of the treats I have given out over the years.
100 Days Smarter Treat Tag and Certificate – The students always enjoy getting Smarties candy for being 100 days smarter – they think it is funny. I like to pair it with this special certificate that students can keep for years to come. Our grocery store sells the Smarties candy rolls in the bulk candy section and you can also find them here on Amazon.
You are Worth More Than 100 Grand Treat and Tag – Since the name of this candy bar goes with our 100 days party theme I had to use it as a treat! I simply attach it to this cute tag!
Crazy Straw Treat with Tag & Personalized Certificate – I like to give these crazy straws as a non-candy treat along with these personalized certificates.
You are 100 Days Brighter Glow Stick – This is another non-candy favorite treat idea. Attach this cute tag to a glow stick and brighten your students’ day before they go home.
