How we scored them

The Shelf Score weighs fit for the reader, contents and edition, value, and the listed reading age or level where one is given. All five picks list a reading age, and three also list a grade level. 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 i spy books for 5 year olds

Reading age and grade level

All five list a reading age marked as from customers. I Spy a Dinosaur’s Eye lists 2 to 5 years with grade level Preschool to 3, the best match here for a five year old. I Spy For Girls lists 3 to 5 years. Construction Vehicles lists 2 to 4 years. Halloween Haunt and Find lists 3 to 5 years but grade level 2 to 3, which disagrees with the reading age. John Deere Farm and Find lists 2 to 4 years with an unusual grade level of 1 to Preschool.

Theme and pages

Themes run from dinosaurs to farms. Dinosaur’s Eye is a Scholastic Reader Level 1 with picture clue riddles, 32 pages. Construction Vehicles covers trucks, cranes and excavators across 39 pages and is book 3 of 35 in its series. John Deere Farm and Find is 32 pages of farm scenes. Halloween Haunt and Find is 32 pages of spooky scenes, and I Spy For Girls is 38 pages of alphabet puzzles. A five year old who reads alone fits the Level 1 reader; one who hunts with a parent fits any theme. See every picture book list for more illustrated options.

Length and edition

Print lengths run from 32 to 39 pages. Publication dates run from 2003 to 2024, with Construction Vehicles the newest at November 2024. Shorter books suit shorter attention spans; the 2024 book has the freshest illustrations. Check the publication date on the listing when choosing between similar themes.

Before you buy

• Check the reading age on the listing, and note when it is marked as from customers.
• Check whether the grade level agrees with the reading age, since two listings here disagree.
• Check the theme against the child’s interests, since a wrong theme gathers dust.
