What is the 100 days of school?

Simply speaking, the 100 days of school acknowledgment is the 100th day of school celebration and milestone appreciation.

I couldn’t really find the origins of how it began. However, my guess is that the 100 days was a great starting point for reflection of how the school year was going. Even conventional schools celebrate this goal mark.

Why is the 100th day of school is a big deal?

Here is why many families choose to celebrate their 100 days of school:

1. The 100th-day mark gives something fun for kids to look forward to.

Yes, celebrations are fun. It’s a totally random time that kids can even choose how to celebrate. It isn’t a heart theme for Valentine’s Day or wearing green for St. Patrick’s Day. The 100 days of a school is a pick-whatever-totally-fun-activities-you-want type of celebration.

2. Cool 100 Day Unit Study Lessons to Incorporate every subject.

I try to do a few complete unit studies for my family per year. They are just really fun for us. We have one theme to work around. We read about it and relate subjects around that one topic.

For a 100-day for school unit, there are countless math concepts to study. Kids can read a book that has “100” in its title. Exercise with kiddos can include workouts with a 100 in them (hardest for me, of course.)

For history, kids can learn about who the President was 100 years ago. Kids can collect 100 things and, yes… count 100 snacks like M&Ms. We love M&Ms in my house. Here are 100th day of school lesson ideas to incorporate different subjects on this day for a whole unit.

3. 100 days of School is a MILESTONE for parents and homeschoolers.

100 days of school may not seem like a big deal for some, but for kids and parents who put their time and effort into lessons and planning, it is a HUGE deal.

It is a time for you to reflect on what you have been teaching, what has been working, and what needs tweaking. It is a great time for kids can review their work and see how far they have come already.

What can your homeschool do for the 100th day of school celebration?

Your homeschoolers can put together hundred-piece puzzles to collect 100 items or use the number 100 for math concepts. Each is a way to celebrate this day. The 100th day has endless possible activities from crafts to various 100th day of school projects.
