15 ways to celebrate the 100th day of school

Are you coming up on your 100th day of school? This momentous occasion is a great opportunity to celebrate 100 days of your students’ hard work—and have fun with the number 100! Check out these ideas and activities that inspire all kinds of learning, for students of all levels:

  1. Ask your students to collect 100 things (such as pennies, paperclips, raisins, buttons, etc.) and bring them to school in a container. Make a display of the collections and have each student write about what they brought. 
  2. Challenge students to tackle IXL Math skills that focus on counting, place value, percentages, and other concepts related to 100. See how close they can get to a SmartScore of 100 on: Count to 100, Add Multiples of 100, Rounding – nearest ten or hundred only, and Rounding – nearest ten or hundred only.
  3. Create a fun 100th Day decoration. Work as a class to create a 100-link paper chain. Students can personalize their links by coloring them, signing their names, or writing a simple equation that equals 100.
  4. Expand your vocabulary! Assign several new vocab words to each student so that you end up with 100 new words and definitions. For older students, consider using SAT/ACT vocabulary or prompting students to find unfamiliar words in the books that they’re reading.
  5. Look to the future. Ask students to calculate what year it will be 100 years from now. Then have them write a story about what they think the world will be like: What new inventions will exist? What clothes will be in fashion? What new animals or planets will we discover?
  6. Research the past. Have each student find and research a notable person who was born 100 years before their birthday. (For a basic biography template, check out this free printable.)
  7. Widen your world. Have your class find the names of two cities in every state so you end up with 100 cities. For an extra challenge, students could also look up their cities’ populations, nicknames, or distance from your school.
  8. Get 100% active: Invite students to run a 100-yard dash, do 10 sets of 10 jumping jacks, or boogie away with 100-second dance parties throughout the day.
  9. Did somebody say STEM project? Place students in small groups and see who can build the tallest cup tower using 100 cups and the engineering-design process. (Psst! You can find free worksheets for this activity here.)
  10. Look for percentage-based statistics in your local paper or a news site. (And take the opportunity to talk about how “percent” means “parts per hundred.”) Then, have students create infographics or presentations with their findings.
  11. Discuss what a centenarian is and have students come up with 100 historical events a current centenarian may have witnessed. 
  12. Brainstorm 100 questions about a particular science topic. Students can then pick a question to research or even reach out to a scientist in that field.
  13. Go on a $100 “spending” spree. Give students a catalogue or retail website to browse and an imaginary $100 to spend. See who can get the closest to spending the exact amount of money without going over. (You can save the sales tax calculations for older students who are studying decimals and percentages.)
  14. Flex your creative writing muscles. Have students write a short story with exactly 100 words. If students need quick inspiration, they can check out these submissions to Reader’s Digest.
  15. List 100 things students have learned this year. This can include academic lessons as well as things they may have learned at home or on their own!
