Description: Explanations and examples of how to implement the Operations & Algebraic Thinking standards in Grade 2. In this section, we'll talk about the connection between the standards in the Operations & Algebraic Thinking domain and the standards in the first cluster of the Measurement & Data (MD) domain. As previously mentioned, the OA standards are also closely connected to place value concepts in the Number & Operation in Base ten domain. Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit.*Teacher Advisor is 100% free.
