Many schools celebrate the 100th day of school by having a “100 Days of School” party.

It is a fun time for students, teachers and parents to get creative and have some fun.  If you are a home school parent you might consider celebrating this occasion with your children, too.

There are so many different activities and crafts that can be done to celebrate the 100th day to make it exciting for everyone!  My kids have enjoyed this tradition and look forward to this day every year!

Some of my favorite ways to celebrate the 100th Day have been quite simple- but memorable!

I think the 100th Day of School is most commonly celebrated in the Kindergarten classroom – it’s a pretty big milestone for being in school full-time for the first time! But it seems like many schools extend the celebration to all grades, which makes it something everyone can look forward to.

We have ideas here for young children and older kids – everyone can join in the fun for this exciting time at school.

When is the 100th Day of School?

This event may vary between schools due to different days off or when school started but it typically occurs at the beginning of February.

To find the exact 100th day, I would suggest grabbing your school’s academic calendar and just counting all of the days school are in session. If you’re lucky, the school will have marked it!

100th Day of School Costume Ideas

Some schools will encourage the students to dress up like they are 100 years old. Here are a few fun ideas:

• Flour in hair
• Gray hair spray
• Suspenders
• Glasses
• Cane
• Go to Goodwill to find older clothing
• Hats with flowers in them
• Dress up like their grandparents

Just for fun, here are pictures of Jack from the past two years:

100 Days of School Items

Have your students bring in a collection of 100 items to show the class. Encourage the students to bring them in a jar or clear bag so it is easy to see.
