How we scored them
The Shelf Score weighs fit, contents and edition, value, and the listed age or level where given. Four of the five picks list an age and a grade level; the math workbook states neither. How we pick explains the weights.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| Smart Start STEM by Evan-Moor | 9.8 | 30 | 22 | 21 | 9 |
| Thinking by Highlights | 9.7 | 32 | 21 | 21 | 8 |
| School Zone Thinking 64 | 9.7 | 30 | 21 | 21 | 5 |
| School Zone Thinking 32 | 9.5 | 29 | 19 | 19 | 4 |
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 critical thinking worksheets for kindergarten
Match the age and grade together
Age and grade do not always line up: the 32 page School Zone book lists reading age 3 – 5 years with grade level 1 – 2, while the Highlights book lists reading age 4 – 6 years, marked as from customers, with grade level Kindergarten – 1. For more choices, see the best workbooks for kindergarten.
Stories or pure puzzles
The Evan-Moor workbook teaches through stories, practice pages and a journal, with an answer key included. The School Zone and Highlights books lean on puzzles: classifying, sequencing, analogies, tracing and writing. For number practice, see the best word problem worksheets for kindergarten.
