Bring historical thinking into the history and social studies classroom with The Big Six - a new Professional Developmentresource from authors Dr. Peter Seixas and Tom Morton"My favourite resource right now is actually a Nelson resource called The Big Six Historical Thinking Concepts. I love it because it is a great support for history teachers as they rethink their teaching to be more about thinking skills. I think this will be a very valuable resource once the new Ontario Curriculum for Canadian and World Studies is released." ¿Kim Crawford, Avon Maitland District School Board
