10 STEM activities to celebrate the 100th Day of School, No Prep Needed

What is the 100th Day of School?

100 days of learning and fun have passed this school year and it’s time to celebrate!

Listen to the article.

The 100th day of school is widely celebrated in kindergartens and elementary schools as a fun milestone between the winter and spring periods. It’s a day that acknowledges and praises the students’ progress. Also it’s a great way of supporting the students’ understanding of numbers, math and time. 

When is the 100th Day of School?

There is not a specific date that marks the 100th day of school. 

The first day of school always varies between mid-August to early September so most schools reach the 100th day of school around the end of January to mid-February. 

What to do on the 100th Day of School?

Some popular activities include counting and displaying 100 items, creating and wearing 100th day shirts, doing 100th day challenges, or making special projects that represent 100 in different ways. You can also have a themed party or make a quiz for your students. The possibilities are endless, however, many of these activities require a lot of preparation. 

If you have had a busy schedule lately and you didn’t have the time to prepare for the 100th day of school, but you still want to mark the day with fun activities, we are here to help. We have gathered 10 fun activities for your classroom that require no preparation:
