I was delighted to read Bob Hazen's message about principled math and the need among teachers (and may I add parents and administrators) to have clearly stated general unifying ideas (principles) that connect math across grades and topics. I had thought for a long time that something like this was needed -- that is why some months ago I asked members of the AMTE list to suggest their candidates for the 'one or two math books that every teacher should be required to digest'. Unfortunately this request generated very few candidates: I suggested Morris Klein's Math for Non-Mathematicians, others suggested Campbell's Whole Craft of Number (OP), and a book by Coughlin & Zitarelli. Now that we have before us Hazen's more detailed description, I hope that others will suggest a few more books that contain at least some of what Bob and I are looking for. Maybe A.N.Whitehead's Intro to Maths?
