Building Thinking Skills is the flagship reasoning series from The Critical Thinking Co., a publisher with over 60 years of history producing PreK-12+ books and apps aimed at strengthening critical thinking as a skill in its own right, on the premise that deeper reasoning improves performance in every other subject. The series moves through six levels — Beginning (ages 3-4) through Primary, Level 1, Level 2, and two titles for grades 7-12 — each covering verbal and nonverbal reasoning, spatial relationships, analogies, and sequencing.
Lessons typically take just 10-20 minutes and require minimal prep, with reproducible student books that include answer keys (except the earliest Primary level). Younger students often need more teacher interaction to work through activities, while older students can generally complete lessons independently. The company also publishes a wide range of companion titles (Mind Benders, Think Analogies, Editor-in-Chief, and more) that many families add alongside Building Thinking Skills as supplements.
Best for families wanting a genuinely secular, dedicated reasoning and logic supplement that strengthens performance across every other subject, rather than a standalone core curriculum.
Strengthens the reasoning skills that support reading, writing, math, and science.
10-20 minutes, easy to fit alongside a full curriculum.
A consistent approach that grows with your student.
