Welcome to The Critical Thinking Consortium

TC² is a non-profit organization of Partner groups and Individual Members.

Each year we support many thousands of educators through a range of face-to-face, online and print resources and services developed around a classroom-proven approach to embedding critical thinking. Our aim is to help students learn to think and think to learn.

October 17, 2014 is the United Nations International Day for the Eradication of Poverty. The October 15 issue of  The Thinking Teacher helps students explore the issue of poverty, consider the consequences faced by people living in poverty and determine actions that can break the cycle of poverty.


We are delighted to announce that TC² writer and developer, Tracey Tinley is the recipient of the Prime Minister’s Award for Teaching Excellence Certificate of Achievement, the second of our colleagues to receive this honour in two years. As well as igniting a passion for learning in her students and fellow teachers, Tracey is a lead writer with the TC² Inquiry-pacs development team. Read more.


History? HERstory! October is Women’s History Month in Canada. The teaching resource offered in the October 1 issue of The Thinking Teacher invites students to determine what daily life was like for pioneer women at the turn of the 20th century using photographs, interviews and even a letter-to-the-editor. You can find this issue in the archives on the right side of The Thinking Teacher page.


We are pleased to announce the release of the first unit of Inquiry-pacs, our new online collection of all-inclusive courses and units in social studies, history, geography and civics that is getting rave reviews from teachers. The grade 5 strand B Ontario social studies unit, Good government and responsible citizenship is now available and the grade 4 strand A unit, Early societies, is planned for November. Several additional units are under development and are coming soon.

What is the difference between partnership and membership?

Partners are organizations like schools and school districts who have joined TC². Educational leaders within these groups often work with TC² staff to provide professional learning programs for their teachers. Employees of these groups enjoy benefits such as free access to our three main online resource collections, discounts on all TC² resources and access to the library of professional resources.

Is my school or district a Partner?

If your district, school or faculty is not a TC² partner, you can obtain the benefits of partnership by becoming an Individual Member.
