Addition and Subtraction with Greater Numbers

•

• Solve Addition and Subtraction problems Rigor p. 75E Conceptual Understanding: • Build on Counting Skills • Find Patterns and Relationships in Addition and Subtraction Equations • Understand 10 as a Benchmark Number Procedural Skill and Fluency: • Add and Subtract Within 10 • Add Within 20 Applications: • Addition and Subtraction Situations Focus Strand: Mathematical Practice Standard #7 and #3 p. 75F 7. Look for and make use of structure. (Topic 2) Recognize and apply the structures of mathematics such as patterns, place value, the properties of operations, or the flexibility of numbers. See complicated things as single objects or as being composed of several objects. First grade students use structure to apply the Commutative Property to find missing addends. Listen and look for students that exhibit the following behaviors: • analyze and describe patterns in numbers • procedures and objects to represent, describe, and work with them in different ways 3. Construct viable arguments and critique the reasoning of others. (Topic 3) Use stated assumptions, definitions, and previously established results to construct arguments. Explain and justify the mathematical reasoning underlying a strategy, solution, or conjecture by using concrete referents such as objects, drawings, diagrams, and actions. Listen to or read the arguments of others, decide whether they make sense, ask useful questions to clarify or improve the arguments, and build on those arguments. First grade students critique the reasoning of others as they determine the best strategies to solve addition and subtraction problems. Listen and look for students that exhibit the following behaviors: • ask questions to understand other people’s thinking • identify mistakes in other people’s thinking • provide suggestions for improving other people’s thinking Focus Standards Curriculum Supports – enVision 2.0 Vocabulary 1.MP.7 1.MP.3
