Suggest me books for a third grade class

Hello—to make a long story short, while visiting a family member who works as a teacher, I discovered that their school no longer has a library. This deeply saddens me as someone who depends on libraries daily.

The family member teaches third grade and I'm considering donating some books for the classroom because I know a great book can lead to a lifetime of reading.

What are some books that would work for a third-grade level? Some series I've considered include Percy Jackson, How to Train Your Dragon, Judy Moody, etc. I'm sure there are more, but I'm not entirely sure what would work.
