" “Problem solving means engaging in a task for which the solution method is not known in advance.” " Principles and Standards for School Mathematics " It encompasses exploring, reasoning, strategizing, estimating, conjecturing, testing, explaining, and proving. " "We only think when confronted with a problem." -- John Dewey Parent Session ISK 2013 Parent Session ISK 2013 Learning Mathematics " For all students to become mathematically proficient, major changes must be made in instruction, assessments, teacher education, and the broader educational system.

Both kinds of The question of which kind of knowledge is most important knowledge are required for mathematical expertise... Instead, we should focus on designing teaching environments that help students build internal representations of procedures that become part of larger conceptual networks.
