How we scored them
The Shelf Score weighs fit for a five-year-old seeking facts, contents and edition, value, and the listed reading age or level. Every one of the five lists a reading age or level from customers. How we pick explains the weights.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| VHC First Encyclopedia | 9.6 | 30 | 19 | 15 | 8 |
| First Big Book of How | 9.5 | 32 | 16 | 15 | 8 |
| The Big Book of Airplanes | 9.4 | 28 | 15 | 15 | 8 |
| Pebbles and the Biggest Number | 9.4 | 27 | 16 | 14 | 8 |
| The Day the Crayons Came Home | 9.3 | 21 | 16 | 15 | 8 |
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.
