My colleagues and I really enjoyed your presentation at NCTM. We have already convinced our principal to pre-order us copies of your new book, but we would also like 4 class sets of the pyramids.
Many presentations talked about problem solving and the benefits of giving students higher level thinking problems, but yours was the only one that really told us how to teach it and scaffold it for students, rather than just modeling what problem-solving looks likes. Thanks.
