Our family has very much enjoyed The Fallacy Detective and had planned to head into the Critical Thinking l and ll once we were finished. With the publication of The Thinking Toolbox what would be your recommendation on sequencing logic materials for a 13-year-old? Leigh Blaylock

Here are our recommendations:

Building Thinking Skills Book 2 — age 10
Building Thinking Skills Book 3 Figural — age 11
Building Thinking Skills Book 3 Verbal — age 12
The Fallacy Detective — age 13
The Thinking Toolbox — age 13
Critical Thinking Book 1, Chapter 2 — age 14 (you could skip this–CT2 has a short review of this chapter)
Critical Thinking Book 2 — age 14 or 15
Introductory Logic Video Course by James Nance — age 15-16
The Art of Reasoning by David Kelley — age 16-17

I have included the ages here, but it is not so much an age requirement for each book as it is a progression. We suggest you progress from Building Thinking Skills to The Fallacy Detective to The Thinking Toolbox to Critical Thinking to Introductory Logic to The Art of Reasoning. There are other books which could replace The Art of Reasoning (Intermediate Logic by Nance, Traditional Logic by Martin Cothran, Material Logic by Martin Cothran,
Introduction to Logic by Irving M. Copi, Critical Thinking in US History) as you see fit. I wish I could eliminate recommending CT1 altogether, but Chapter 2 of CT1 is not covered in The Fallacy Detective or The Thinking Toolbox, and it is an important chapter. CT2 DOES have a short review of what you learned in Chapter 2 of CT1, so if you are short of funds, you PROBABLY could get away with skipping CT1 entirely and just go directly to CT2. The Thinking Toolbox can be used after or before The Fallacy Detective.
