How we scored them

The Shelf Score weighs fit for a young reader, contents and edition, value, and the listed reading age or level. All five list a reading age. How we pick explains the weights.

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.

How to choose the best children’s books about water

Match the reading age

The five range from reading age 2-6 (Water Is Water) to 4-10 (A Drop Around the World), with We Are Water Protectors at 3-7 and both Hey, Water! and Drop at 4-7 to 4-8. Start with the youngest age in your house. For more read-alouds, browse our picture books.

Cycle or conservation

Four picks teach the water cycle, from Drop’s adventure to Hey, Water!’s backmatter. We Are Water Protectors is different: a rallying cry honoring Indigenous-led movements to safeguard water. Pick science for school, or the protector story for heart. For more animal and nature reads, see our children’s books about wolves.

Story or nonfiction

Drop follows a water drop character, while Hey, Water! is nonfiction with accessible backmatter on the water cycle and conservation. Both teach, but the story keeps younger kids turning pages longer.

Before you buy

• Check the reading age: the five range from 2-6 to 4-10 years.
• Confirm the page count: 32 to 48 pages.
• Note the awards: We Are Water Protectors is a Caldecott Medal winner per the listing.
