We paint T-shirts with 100 stamps and acrylic fabric paint and wear them on the 100th day. We have found that it is easier if you use stamps that have five of something on one stamp. This also helps them in counting by fives. Christy Cooper, Gruver, TX, First grade


One of our favorite activities is trying to collect 100 "autographs" before the end of the day. Be sure to set rules about going to the office, etc. L. Murray, Pacifica, CA, Second grade

A few ideas I used:

  1. Our class ate 100s in the morning by cooking sausage links and mini-bagels and lining up one sausage and two mini-bagels to form 100.
  2. I broke the class into groups and gave each a 100-piece puzzle. They had a race to finish the puzzles.
  3. Students worked in pairs with 100 mini-marshmallows and toothpicks to design a sculpture. Jennifer Farrand, Canton, MI, First grade

At my school we have observed 101 days of school. We had the children make dalmatian t-shirts (white shirts with black spots), we made dog headbands and had them make 101 spots on the ears, we painted their faces and made treat bags with 101 treats in them for them to eat while watching the movie 101 Dalmatians. This year you could even celebrate 102 days of school with the release of the new movie! Shari Lawson, Hampton, VA, First grade

We have a 100-day salad. Each child bring 100 pieces of something edible. Then we mix it and each student gets some of the salad to share. Juli Michaels, Burlington, WY, First grade

We made 100-day badges to wear all day. We made a sign showing the many ways that we could count to 100. We also brought in ten different snacks. Each child chose ten pieces of each of the ten snacks. We then ate our 100 snacks. It was a lot of fun. Sandy Jo Heller, Ocala, FL, Kindergarten

We floated 100 balloons in the main hallway for a festive look. Each class did activities geared for their grade level. Fifth-grade teacher, Birmingham, Alabama

I do a lot of the usual things such as bringing in a baggie filled with 100 items, writing 100 words, etc. I also like to have my first graders do a dot-to-dot with 100 numbers. I really like the idea of 100 valentines and sending them to the hospital. Amy, Tucson, AZ, First grade

For our 100th day of school, both kindergartens get together and we complete different 100 activities. Examples: 100-piece puzzle, create a special 100-piece snack, and draw a picture of what we will look like when we are 100 years old. Then we have lunch together and watch a special movie in the afternoon. It's a big party day! Kindergarten teacher, Glenview, IL

We write stories using 100 words, count 100 shells, keys, etc..., eat a cake with 100 M&M's on it, and decorate badges with 100 jewels. Denise Bowers, Hilton Head Island, SC, First grade

Make t-shirts with 100 designs on them. Make a trail mix with 100 food items. Flip coins and roll dice for probability. Tammy Hernandez, McDonough, GA, Second grade

We started out the day by counting 100 pieces of cereal, adding milk, and eating it. It was so much fun! We played 100-second games and 100-word games. For math, we had ten stations set with ten types of snacks such as M&M's, popcorn, raisins, etc. The students went to each station and grabbed ten pieces. We sorted, counted, and estimated. What a wonderful day! Angela Kiser, Durham, NC, Second grade

I send home an 8 1/2" x 11" piece of posterboard cut out in the shape of 100. Each student glues on 100 of something and brings it to school on 100's Day to share. We also send out a message in our daily bulletin about the 100 signatures that we would like to collect. Each visitor signs our banner and gets a sweet treat. My class is always anxious to see where 100 feet will take us in our school by cutting out our footprints and lining them up down the hall. We also enjoy several 100's Day stories throughout the day, and make necklaces out of 100 Cheerios. Jodi Morgan, Denton, MT, First grade

I have my second graders dress up as centenarians, people who are 100 years old. They list 100 words they know. They bring in 100 items and we sort them into 2 equal piles, then four, five, and ten equal piles. Pennies, cotton balls, uncooked macaroni all work well. Using 100 pieces of cut-up paper, they make the numeral 100 on construction paper. They make a 100th-day book, in which they write about various 100's topics. With a partner they roll a die 100 times and chart what number the die lands on and then figure out which number it landed on the most and least often. Amy, Orlando, FL, Second grade

Our first graders have a 100th-Day Celebration. On about the 90th day of school, we send home directions for the children to create "100 Collections" and bring them in on the 100th Day. We then have a "100 Collection Show" and invite the whole school and families. The kids love to answer questions about the collections (which are in groups of five or ten) and show off their projects. We then make a special 100th-Day "trail mix" that all the kids have contributed to by bringing in 100 things for the snack. We also have 100th-Day Centers, like making necklaces with 100 pieces of cereal, or making 100 glasses, or patterning with a 100 grid. These are combined centers with our kindergartners and vary from year to year. We make sure that photos (no names, of course) are on the school's Web site, are included in the district newsletter, and we always STRONGLY urge our principal and superintendent to attend the 100 show! Michelle Enser & Mary Price, West Valley, NY, First grade


  1. Students write as many words as they can think of in 100 seconds. They share lists and see who has the most unusual words.
  2. Students try to hold their breath for 100 seconds.
  3. Build a log house with 100 toothpicks.
  4. Creative Writing: If you were given $100, what would you do with it? If I am living 100 years from now, this is how my life will be...
  5. I have a paper with 100 dots. Students can connect the dots to make a design or picture, or they can play the "squares" game. Each partner takes turns connecting one dot to another. If the person finishes a square they put their initials in the square and make one more line. The person with the most squares is the winner.
  6. PE activities: Do an activity for 100 seconds, like hopping on one foot or jogging in place.
  7. Do Sustained Silent Reading for 100 minutes throughout the day.
  8. Students bring a collection of 100 items in a baggie (paper clips, M&M's, etc.).
  9. A worksheet has the words ONE HUNDRED printed at the top. Students try to see how many words they can make using only those letters. Debi Fielding, Colfax, WA, Third Grade

I actually celebrate 101 days of school and turn it into a 101 Dalmatians day! I have the students each bring in 101 small food items (peanuts, Chex cereal, Cheerios, etc) and we mix them all together to make a huge class party mix. We eat that while watching the 101 Dalmatians movie. We also have Dalmatian bingo and other games we play. Lou, New Orleans, LA, Second Grade

For a home project, each student creates a 100-item T-shirt. For example, my shirt has 100 safety pins attached to it. A student once sewed 100 buttons on a shirt. The students also create a 100-item project. For example, a student once built a house out of 100 Popsicle sticks. Another student wrote his name with 100 stickers. It is a lot of fun to see the creative things the kids come up with. Name withheld

In the past, I have made a 100 out of a large heavy cardboard box and cut holes out of the zeros so that the children can walk through them when they come into school. Also, I lined the hall with 100 balloons that I blew up with a rented machine. The children had a ball. P. Hendrickson

We make 100 valentines to send to local hospitals, Headstart Centers, and retirement homes. Eileen Hardin, Metairie, LA, K-2

My first-grade bilingual class and I write down 100 acts of kindness onto small heart-shaped cutouts and glue them onto a chart. We make a list of 100 words we can spell. We make eyeglasses in the shape of the number 100. We join 100 chain links and measure how far it will reach. (The students also enjoy measuring the teacher!) Lastly, using a measuring cup, we estimate how high 100 spoonfuls of water will reach. (Food coloring makes this fun.) Michelle DeLuca-Serpenti, New Rochelle, NY, First Grade

Students in my class sew books together the week before the 100th day. They decorate the covers and then have a week to fill the book with names of 100 people they know. They begin with the names of the students in our room and are only allowed to get other schoolmates' names at recess and lunch. A cover letter goes home with each child so the parents are aware of the project. They are asked to help their child with this task. On the 100th day we have a celebration sharing our books. Cheryl Beauregard, Berlin, MA, Third Grade

Special Snacks: Put 100 Cheerios, 100 raisins, 100 mini-marshmallows, 100 kernels of popcorn, 100 fish crackers, 100 pieces of Chex cereal, and 100 pretzel sticks into a container. Mix it up and enjoy!

Hundreds Olympics: Assign each student a partner, and tally how many of each of the following activities the kids can do in 100 seconds: jumping jacks, sit-ups, push-ups, hops, laps around the gym, hand claps, etc.

100th Day Sing-a-long: Bring all the children in your school or grade - over 100 children - into the gym. Tape ten large squares to the floor. Then sing "One little two little three little children/Four little five little six little children." As you sing, bring the children into the squares until they are all full. (You should make sure in advance that the squares are large enough to fit ten children!) That way, the children can see what 100 looks like. It's great fun for children from ages four to ten.

100th Day Banner: On the 100th day of school, stretch a banner with the number 100 across one of the hallways in your school. Cut out the zeros, and glue 100 items around each numeral - things like stickers, shapes, photos, etc. All day, students and staff will have to walk through the zeros to get from one end of the hall to the next!

School Decoration: A hundred days is a long time, but each day has a lot of time in it as well. Every 24 hours is filled with things to do. You and your children and a lot of children from other classes (at least 100 total) can show how far 100 days of 24 hours each can stretch down your hallway if you use a roll (or so) of adding-machine tape. Use a meter stick to measure out one-meter sections on the tape with a marker. Then tape 100 meters of tape down the sides of the hallway at a convenient height for your students. If you run out of hallway, just come back up the opposite side. The beauty of using a meter stick is that it has a hundred of something on it as well. When the hallway is completely papered, assign each child one meter-long strip of tape. Have them break their meters down into 24 hours, starting at midnight. Now all they have to do is write in all the activities of a typical busy day in the proper time slots. They can add in illustrations above or below your time tape to dress it up. Don't forget to let them go check out each other's handiwork!

100th Day Raffle: For each assignment that students complete and earn a score of 100 on during a week, they can earn a chance to win a jar filled with 100 pennies. The raffle can be held at the end of the school on the 100th day.

Show & Tell: Ask students to bring into school their collections of 100 objects. Kids can bring in buttons, stickers, Legos, Cheerios, blocks, small balls, rocks, baseball cards, and pogs.
