What do you hear? Classrooms are rarely quiet places! Scraping chairs, buzzing pencil sharpeners and coughs and sneezes that linger all year are just a few of the many sounds you might hear. But the most important sounds by far are the voices of your students. This month's issue of The Thinking Teacher offers resources for strengthening your students’ ability to respectfully share, listen, question and respond to the ideas being shared in your classroom community.


How can we ensure that our students have the tools needed for success? The Competencies Toolkit, a new teaching resource from The Critical Thinking Consortium, provides the basis for teaching tools to develop student competence to think, communicate and act. Learn more about this new publication.


We have posted two new tip sheets - Promoting critical thinking in science and Tweaking questions and tasks to deepend critical thinking in science. Invite students to make reasoned judgments about virtually everything they do in science, and to think more deeply about science topics by tweaking the questions and tasks you use. You can find these tip sheets under the Subject areas tab on the Tips for Teachers page.


We are excited to announce that our new grade 2 Inquiry-pac unit Changing Family and Community Traditions is now available. This online package provides everything you need to implement unit 2A of the new Ontario social studies curriculum through exciting, ongoing inquiry. Licenses for this unit are now available for purchase, as well as the grade 4 Early Societies, the grade 5 Good Government and Responsible Citizenship and the grade 6 Community Stories and Canadian Identity units.


NEW RESOURCE! Recognizing an Historic Injustice: Canada's First National Internment Operations explores the events, causes and consequences of the internment of thousands of individuals in Canada during the First World war era. It has been made available for free courtesy of a grant from the Endowment Council of the Canadian First World War Internment Recognition Fund. Visit our Pivotal Voices page to download a free PDF version or go to our online shop to order a print copy for the cost of shipping.

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.
