Dressing Up for the 100th Day of School
To create an engaging and lively atmosphere, encourage students to dress up. If you want to make them smile even more, dress up, too! Send a note home to parents explaining 100’s day and asking them to dress up.
Give them suggestions, such as glasses, sweaters, and long dresses for girls, and button-up shirts and suspenders for boys. Add some baby powder to your hair to make it look gray. Tell the kids to practice an older adult’s voice and posture.
Another fun way to dress up is to create and wear 100’s day shirts to school. Ask students to bring in a shirt with 100 things on it, and ask parents to help prepare this at home. Some ideas include 100 buttons, pins, pom poms, stickers, and more.
100 Days of School Activities
A well-run 100’s day celebration requires some time to prepare materials in advance. There are many free online activities and classroom ideas. Ask parents for donations; they are usually more than willing to send in an item to share.
Get the materials for our 100 days of school activities ready to go on a table. Being organized is key to a successful day when so many new things are happening.
100th Day Hats
These 100th Day Hats allow students to share what they have done during their time in school so far. It’s a fun way to show off everything they have accomplished and wear the hat around all day. There are also number strips to hang around the hat so they can practice counting to 100!
100 Days of School Snack Recipe
Have kids take turns coming to the table to count out 100 pieces of food for your 100th-day snack. Count out each type in groups of 10 using 100th-day mats. You could use any snacks you want.
Choose a mix of healthy snacks and treats for our special day. Some popular options are pretzels, grapes, m&m’s, marshmallows, jelly beans, fish crackers, bunny crackers, chocolate chips, graham crackers, and Cheerios.
You can create these mats and laminate them for durability so that they can be reused each year. To make the mats, cut 11″x 17″ pieces of cardstock. Glue on 10 circles in any color and size you like.
Add a label to the center and laminate. Students can place 10 snacks in each circle. Once they have counted ten groups of 10 snacks, they have 100 snacks to eat! Yummy!
100th Day Collections
A favorite activity for the 100th day of school is sharing collections of 100 things. Teachers can send home a letter to parents encouraging them to help their child collect 100 items. The collection can be brought to school in a box or bag with tally marks showing that there are 100 items inside, making it a fun and collaborative project for families to complete together at home.
Easy 100th Day Cereal Necklaces
Another fun activity is creating Fruit Loop necklaces. This activity requires a box of Fruit Loops cereal, string, and paper plates. Taping one end of the string to a desk can help prevent the cereal from sliding off while students work. Each student is given a paper plate with enough cereal to complete their necklace.
Students can count the cereal in groups of 10 and add a small paper marker onto the string after each group to help keep track. Once the necklace is finished, the ends of the string are tied together, and students can wear their necklace before enjoying it as a snack.
Which 100 Days of School Stations Should I Choose?
Later in the day, students can participate in fun, hands-on STEM and independent 100th-day-of-school activities. The class can be divided into small groups of up to 4 students who rotate through stations set up in advance. Each station includes a mental or physical challenge for students to complete.
One of the simplest stations to prepare and one of the most engaging for students is the 100 Cups challenge. Students are tasked with building something using all 100 cups. This activity encourages teamwork and communication as students work together to plan their design and figure out how to keep their structure standing.
Several of the station setups can include items pulled from math tubs and center bins. Teachers can count out 100 items ahead of time and place them into bags for easy prep. Common station materials include small wooden blocks, LEGO pieces, and Unifix cubes.
At each station, the challenge is to use all of the pieces in the bag to build something. This encourages students to problem-solve, plan, and work collaboratively while reinforcing the concept of counting to 100 through hands-on activities.
If I Were 100 Year Old Writing Activity
Brainstorm with students what they might be like or do when they are 100 years old. Let them get as creative as they would like with their writing and drawing. After they each take some time to write, share aloud for a fun discussion.
100th Day Action Tasks
Give students some fun tasks to complete throughout the day. They have to do 10 of each for a total of 100 by the end of the day. It can add some chaos, but it’s worth it to watch them smile as they try to tackle their actions before the day is through!
Provide Kids With a 100th Day Certificate
As students get ready to leave the classroom, award them with a 100th day of school certificate! Make the day even more exciting by turning it into a true celebration of their learning. Laminate the certificate for extra fun!
