Fourth-grade books sit at levels R18–R20. A book is around a thousand words, split into sections with headings; stories let the reader work out how a character feels without being told, and some non-fiction takes a side and sets out why.
The grades are a guide, matched to the levels children read at school in the US (R18–R20 on the 7ESL ladder). Children read at different speeds, so start where the quiz feels comfortable and move up one level at a time. Older beginners and adult learners use the same books.
What the 25 books for 4th grade are about: how things work (4), jobs & community (3), biographies (3), earth, water & weather (3), adventure & mystery (2), and 7 more topics.

Questions about 4th grade reading books
What reading level is 4th grade?
R18 to R20 on the 7ESL ladder – levels Q to S on the Raz-Kids scale.
Why do some books argue a case?
Fourth graders learn to notice what a writer wants them to think. A book that argues fairly, and says what the other side believes, is the best practice for that.
Do the books have audio?
Yes. A narrator reads every page, each word lights up as it is spoken, and characters have their own voices.
