Model with mathematics. Use appropriate tools strategically. Attend to precision. Look for and make use of structure. Look for and express regularity in repeated reasoning. Learning Targets Knowledge Reasoning Skill Products Facts and concepts we want students to know. Use what they know to reason or solve problems. Use knowledge and reasoning to act skillfully.
