Hundredth Day of School celebrations are often geared toward the primary grades. If you teach in a K-5 school though, the celebration probably extends to the entire school. That leaves intermediate teachers searching for 100th day activities for upper elementary students.

Don’t you worry though. There are plenty of fun activities that you can do on the big day! The best activities are those that combine learning standards with 100th day fun. I will be sharing some of my favorite 100th day activities for upper elementary with you today!
100th Day of School Centers
I love using learning centers all year long, but special occasions like the 100th day are perfect days for learning stations. You can set up the entire day with a set number of learning center activities for students to rotate through. You can also create center activities for different subject areas. Do what works for you and your classroom! Here are some of my favorite 100th day center ideas.
- 100 total math problems. Stock the center with number tiles, base ten blocks, calculators, etc. and have students create math problems that equal 100.
- “If I had $100” writing activity. Have students write about what they would do if they had $100.
- 100 blocks. Give students (or partners/ groups) 100 building blocks. See what creations they are able to come up with!
- 100 words. Let students brainstorm 100 words to fit into categories. Categories could include 100 nouns, 100 verbs, 100 animals, 100 countries around the world, 100 colors, etc.
- $100 shopping trip. Give students a challenge to plan a party and shop for the supplies using only $100. Bring in sales ads from local stores or use online options.
- 100 miles from here. This is a great activity for practicing map skills! Use a paper or digital map to find locations that are 100 miles away. Research things to do/ see in that area.
- My 100 year old self. Imagine you live to be 100 years old. What is your life like? What about the world around you? Have students write about it.
