“Peter Liljedahl has written maybe the most important and practical book that just can't be ignored by teachers of math. As a sixth grade teacher, I have searched for a book that could help me "put it all together" to complete a move away from the repetitive ‘I do, we do, you do’ method of math instruction that is STILL so prevalent in our schools. Even teachers who may have in the past resisted changing their practices because they just weren't sure how will be able to do it with the help of the practices outlined in his book.”
