Full Curriculum Solutions Teaching Critical Thinking
We design critical thinking into ALL of our full curriculum products. This not only helps students transfer critical thinking skills to other areas of their lives, it improves the effectiveness of the lessons. Critical thinking requires deeper analysis of the lesson. Deeper analysis produces deeper understanding, resulting in greater engagement and retention of the lesson.

Each product listed below provides a complete curriculum within grade range and subject, and meets state and national standards set by the Department of Education.
"If we teach children everything we know, their knowledge is limited to ours. If we teach children to think, their knowledge is limitless." - Michael Baker, President

Customer Testimonials:

"I have literally looked all over the world for a good Critical Thinking program and the best one I found was The Critical Thinking Co. I'm using it in all the grades, kindergarten to 12th grade."
- Dr. Daithi O Murchu, New Castle West, Ireland

"The most positive characteristic of the Mathematical Reasoning books are the higher order thinking skills that the content encourages. As an educator, I can appreciate that the skills involve multi-steps and hands-on manipulation."
- iParenting Media reviewer

"I have been teaching for 38 years. I started using your materials in the 1970's while working with gifted students. The Critical Thinking Co. materials have provided a constant challenge for my students. The Mind Benders were one of their favorite activities. I have continued to use your curriculum materials for more than 30 years. I have made it a point of sharing your critical thinking books with other teachers. Thank you for enhancing the minds of youngsters!"

Common Core and The Critical Thinking Co.

The skills and concepts taught in our products are the result of our surveys of state and national educational standards. We will continue to avoid any topic in any set of standards that is overtly political. We firmly believe it is not our place to attempt to influence the politics or values of any student. Most Common Core Standards are already found in various state standards, but the list of Common Core Standards is not complete. Since a large number of states (45) have signed on to Common Core Standards, The Critical Thinking Co. will now include Common Core Standards in its broad survey of state and national standards to determine the skills and concepts taught in each grade level subject, but we will not base our products solely on any one set of standards. Our products are written with longevity in mind, considering the tried and true practices of teaching children to read and think for themselves. Those of you who have trusted us in the past can rely on us to continue to teach beyond the standards in the future. Please help us spread the word.
