Description: Explanations and examples of how to implement the Operations & Algebraic Thinking standards in Grade 2. These guides are designed to explain what new, high standards for mathematics say about what students should learn in each grade, and what they mean for curriculum and instruction. The second part shows how Operations & Algebraic Thinking relate to representing and interpreting data in Grade 2. We strongly suggest tackling these problems yourself to help best understand the methods and strategies we're covering, and the potential challenges your students might face. Much of students' early learning in mathematics revolves around the operations of addition, subtraction, multiplication and division. But as we know from experience, being able to calculate an answer isn't enough.
