How we scored them
The Shelf Score weighs fit for a 4th grade reader, contents and edition, value, and the listed reading age or grade level. All five listings give a reading age and a grade level. How we pick explains the weights.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| The Skull | 9.7 | 33 | 21 | 20 | n/a |
| Looking for Bigfoot | 9.7 | 32 | 20 | 20 | n/a |
| Fractions in Disguise | 9.7 | 30 | 20 | 20 | n/a |
| The Wild Robot on the Island | 9.7 | 30 | 21 | 19 | n/a |
| Edward the Emu | 9.6 | 28 | 19 | 19 | n/a |
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 picture books for 4th graders
Match the grade level, not just the age
The Skull lists grades 1 to 4, which covers 4th grade directly. Looking for Bigfoot lists grades 2 to 4 as a Step into Reading Step 4 book. Fractions in Disguise lists grades 2 to 5. The Wild Robot on the Island lists Preschool to 3, and Edward the Emu lists Preschool to 3, both aimed younger. For a 4th grader reading at grade level, the grade-4 picks fit best; the younger ones work for a struggling reader who needs an easier win.
Length and staying power
The Skull runs 112 pages, far longer than a typical picture book, which suits a 4th grader ready for more text. The Wild Robot on the Island and Looking for Bigfoot are 48 pages each. Edward the Emu and Fractions in Disguise are 32 pages each. A longer book holds a confident reader; a shorter one finishes in one sitting for a reluctant reader.
Pick the subject that pulls them in
The Skull is a Tyrolean folktale about courage and friendship, with a macabre edge that appeals to older kids. Looking for Bigfoot investigates whether Sasquatch descends from the extinct giant ape Gigantopithecus. Fractions in Disguise teaches simplifying fractions through an adventure story. The Wild Robot on the Island adapts the robot adventure in full color. Edward the Emu is a rhyming comedy. Let the child pick the subject; a 4th grader reads what interests them.
