Writing Prompts for the 100th Day of School

Here are the prompts included in the set, some silly, some reflective, and all easy to use as a quick morning warm-up.

If I had $100…
Kids love this one. Mine immediately started listing snacks. It’s a fun way to see what they value or what they find exciting.

I wish I had 100…
A great imaginative prompt. I’ve seen everything from “100 puppies” to “100 snow days,” and the explanations are usually hilarious.

What new skill will I learn in 100 days?
Simple planning prompt. Works well if you want to talk about goal-setting in a light way.

Living 100 light years away
Always a hit with space-loving kids. Let them describe the planet, who lives there, and what daily life might look like.

If I were 100 years old…
Kids tend to exaggerate in the funniest ways. Great for perspective taking.

The Earth in 100 years
Ideal for older elementary. Quick predictions about tech, nature, or daily life.

Life 100 years ago
A short research prompt. Even one photo comparison can give kids something to write about.

The 100th President of the United States
A fun creative exercise where kids invent a future leader and describe their personality and accomplishments.

If you want an extra activity, the kids also enjoyed the 100 days of school crown printable.

If the World Were 100 People Activity

One of the pages in this set is inspired by the book If the World Were a Village, which shows the world as a group of 100 people so kids can picture big numbers more easily. It fits nicely with the 100th day theme and helps make “100” feel more concrete.

When we used it, it sparked a great conversation. Kids made quick predictions about everyday things, languages, ages, access to basics, and then compared their guesses with the real numbers from the book.

It isn’t a writing prompt on its own, but it works well as a warm-up. Kids can jot down answers or reflect with a simple question like “What surprised you the most?”

More Fun Writing Prompts

If you like keeping a few seasonal writing choices on hand, these sets fit nicely into the rest of the school year.

Kids who enjoy themed journaling usually like working through my Valentine’s Day writing prompts as February rolls in.

When March gets closer, these St. Patrick’s Day writing prompts add a simple seasonal twist to your daily writing routine.

If you want one more imaginative option, the If I Were a Leprechaun worksheet always brings out funny, creative stories.

For spring, my Easter writing prompts work well as a quick warm-up on busy mornings.

And if you need something flexible for everyday use, the first grade writing prompts give younger writers an easy place to start.

If you like adding a quick read-aloud to the day, these books pair well with the writing prompts and keep the “100” theme going:

100th Day Worries – Kids relate to the main character’s struggle to find 100 of something to bring to school. It opens up a nice discussion before writing the “I wish I had 100…” prompt.

If the World Were a Village – This one inspired one of the pages in the printable set. It helps kids understand big numbers in a simple, visual way and works beautifully as a warm-up for the discussion sheet.
