25 Addicting Chapter Book Series For Third Graders

Chapter book Series for 3rd Graders pin

Looking for the perfect chapter book series for your 3rd grader?

There are so many great series out there for early readers!

Your book list probably already includes some great books though. There are the classic books, such as The Boxcar Children and everything written by Roald Dahl. And then the more modern, popular books like Harry Potter. 

I didn’t want to provide a list of obvious choices you’ve already heard of though. 

Below you will find a lot of fresh, new options, but I also included a good number of classics to balance out the list. 

How To Pick The Best Book Series For Your 3rd Grader

If your younger readers aren’t chomping at the bit to start their next book…then maybe you need some help picking out the best books to bring out their love of reading. 

Especially if this is their first book with chapters, you’re going to want it to be a good experience.

Below are my tips to help you find the perfect book this school year!

1. Try Graphic Novels

Graphic novels are a wonderful way to help elementary school-level readers connect with books!

Seeing the images and less words on a page helps to bring the story to life, engage their interest, and keep them going to the end. 

Many of the below books have pictures, but #16 is a good choice if you think graphic novels are where you want to start.

2. Choose A Main Character They Can Relate To

This will probably not surprise you, but if you have a boy who loves sports and dirt…they might not enjoy a book about a little girl who turns into a mermaid. 

And a girl who gravitates towards unicorns and princesses…may not enjoy a book about zombie goldfish. 

Of course those are stereotypes, but you know your kid and what makes their eyes sparkle.

Each of the books below has a detailed description to give you a solid snapshot of what the books are about. Try to think of what they would love, even if it’s not one of your favorite books.

3. Find Out What Their Best Friends Are Reading

Peer pressures is sometimes a good thing. 

Reading the same books as their peers might give your kid some much needed motivation to dig into a book. If their good friend is into it – it can’t be that bad, right?

This is actually how my own daughter went from casual reader to an avid reader!

4. Pick A Book That is Part of A Series

Since you’re already searching for a chapter book series, you’re ahead of the game!

A great series can keep younger readers engaged and coming back for more.

They will fall in love with the characters and become invested in the story. But when the book is over, they can just reach for the next one in the series!

No need to start searching for a new book or author.
