This document discusses creating learning targets for mathematics lessons. It provides guidance on writing rigorous learning targets that address student needs and curriculum standards. Teachers are encouraged to identify the big ideas or concepts in topics, beyond just the topics themselves. A process for designing learning targets is outlined, including defining essential content and reasoning processes, describing strong student understanding, and stating the target. Examples are provided of modeling the process for specific math concepts and problem-solving strategies. Technologies for lesson planning, capturing student thinking, and facilitating problem solving are also introduced.
