100 Days of School Shirt Ideas

Our favorite school project has to be the 100th Day of School Shirt.  It has been called 100 days of school shirt or “wow, we survived this long?” {giggle}.

I realize that this takes on a WHOLE NEW meaning in 2021.  

We should be celebrating this more than ever!  So, while some of these 100 school days shirts are presented as “in-person” and group ideas, think about the fun of making a day special at home as well if that is your situation.

What is special about the 100th day of school?

Most school year calendars consist of 180 days so when the 100th day of school rolls around, the year is over 1/2 done! It is a fun time to reflect on some of the major accomplishments that have been achieved in the school year especially when it comes to counting and math.

What is a 100 day shirt?

Why do schools celebrate the 100th day of school?

While it is most common in grade 1, other grades celebrate the 100th day of school as well: Pre-K, Preschool, Kindergarten and older grades. It is a fun way to celebrate that more than half of the school year is over and concentrate on some of the lessons already learned in a fun way.

What is the 100th Day of School?

Many elementary (and some middle) schools ask students to celebrate the 100th day they have attended school each year by wearing a shirt or costume with 100 items attached.

This is a fun project for students and parents to do together.

In 2021, many kids will be celebrating the 100th day of school from home with virtual lessons and bringing some celebration “normalcy” could be really uplifting.

When is the 100th Day of School?

The date of the 100th Day of School is usually celebrated in early February. The exact date will vary, depending on your school calendar.

You can find the expected date by counting the days your kid has had school, according to their calendar.

Classroom teachers and schools will typically send home information about their specific 100th Day celebrations.  If your school doesn’t do this, do it the old fashioned way…grab a calendar and get counting!

What do you put on a 100th Day of School shirt?

We’ve seen all kinds of creative projects for the 100th Day of School — one year, a student in my son’s class glued 100 army men to a cape for his costume!

Band-aids, Legos, pom poms, googly eyes, and stickers are great places to start. 

The Best Glue or Adhesive for a Kids’ 100 Day Shirt

I like Aleene’s Fabric Fusion Permanent Fabric Adhesive which works well for fabric to fabric gluing, but also can glue plastic to fabric as well.

Do I have to use a shirt?

Most students choose to use a t-shirt to attach items to, but the point of the project is to get creative!

We’ve seen aprons, hats, and capes all with 100 items attached.  

If your kid is taking classes virtually, maybe a hat would work best!

What if I want to do something different for my 100 Day Shirt?

No problem.

You can start with the ideas we’ve put together, or make your own really easily.

Most 100 days of school shirts simply have 100 items, and some even add a cute saying to take their design to the next level.

Love this shirt! “Eye” Made it to 100 Days shirt idea using googly eyes!

When my son, Andy, was in kindergarten, he was obsessed with Pokemon. So, of course, we spent hours cutting out felt lightning bolts and a Pikachu face to put on his 100th day shirt. But when the morning of the 100th day of school came, my poor little guy was burning up with fever and couldn’t go to school. 

He was so upset that he had to miss the parade, that we had to have our own 100th Day of School celebration at home. I was sad for him that he had to miss celebrating with all his friends, but I think our fun at home was a way better option.

Speaking of Pikachu…. Check out these creative school shirt ideas from some of Andy’s friends…

I love this 100 days of school shirt idea even though it is more of a “100 days of school apron idea” which makes sense because gluing 100 actual plastic dinosaurs to a t-shirt might make a physics problem.  This apron idea is super cute and solves the issues.
