Description: Explanations and examples of how to implement the Operations & Algebraic Thinking standards in Grade 3. 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 first part gives a "tour" of the standards for Operations & Algebraic Thinking (1.OA) using freely available online resources that you can use or adapt for your class. The second part shows how Operations & Algebraic Thinking relate to representing and interpreting data in Grade 1. 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.*Teacher Advisor is 100% free.
