I never knew the 100th day of school was a thing until my kids started Elementary school. What is the 100th day of school and why is it special?? We didn’t do that when I was in school – so I did a little digging.

I found some fun information on verywell.com, see below:

What is the 100th Day of School?

The 100th day of school is literally the 100th day of the school year. More importantly, it is a great way for elementary school teachers to celebrate the various mathematical concepts that can be taught using the number 100. From the very first day of school, classes begin keeping track of the number of days they’ve been in school in anticipation of the 100th day. It’s this anticipation that is actually the first math lesson, as the days are often marked using coffee stirrers or Popsicle sticks, ten of which become a “ten bundle,” paving the way to counting by tens and ones.

When is the 100th Day of School?

The 100th day of school will vary from school to school, depending on when school started and whether or not there were days off for teacher workshops or inclement weather. Most classes end up celebrating the 100th day of school sometime in February, usually right around Valentine’s Day.

What Will my Child Do on the 100th Day of School?

There are hundreds of activities and lesson plans devoted to the 100th day of school and many books written to help celebrate the day.

At our school, only the Kindergartners celebrate the 100 days with a shirt. ONCE AGAIN, Pinterest to the rescue. There are TONS of ideas out there so it’s a fun activity with the kids to pick one. My daughter and son, of course, wanted very different things – my daughter is usually more complicated. Last year we went for buttons – and of course we just couldn’t place 100 buttons randomly on the shirt – it had to have a picture. We went with a flower! It’s not as easy as it seems to get EXACTLY 100 buttons into the shape of a flower. I recommend starting with the flower and ending with the stem and leaves. If you come up short you can always extend the stem or add a leaf!! For my son, we did a small 100 piece jigsaw puzzle – Star Wars, of course.
