The focus in Grade 2 is on the following four critical areas:
- Extending understanding of base-ten notation
- Building fluency with addition and subtraction
- Using standard units of measure
- Describing and analyzing shapes about attributes of, and composing and decomposing geometric shapes
Overview of Grade 2 Standards
Operations and Algebraic Thinking
- Represent and solve problems involving addition and subtraction(2.OA.A.1)
- Add and subtract within 20 (2.OA.B.2)
- Work with equal groups of objects to gain foundations for multiplication(2.OA.C.3, 2.OA.C.4)
Number and Operations in Base Ten
- Understand place value (2.NBT.A.1, 2.NBT.A.1.A, 2.NBT.A.1.B, 2.NBT.A.2, 2.NBT.A.3, 2.NBT.A.4)
- Use place value understanding and properties of operations to add and subtract (2.NBT.B.5, 2.NBT.B.6, 2.NBT.B.7, 2.NBT.B.8, 2.NBT.B.9)
Measurement and Data
- Measure and estimate lengths in standard units(2.MD.A.1, 2.MD.A.2, 2.MD.A.3, 2.MD.A.4)
- Relate addition and subtraction to length (2.MD.B.5, 2.MD.B.6)
- Work with time and money (2.MD.C.7, 2.MD.C.8)
- Represent and interpret data(2.MD.D.9, 2.MD.D.10)
Geometry
- Reason with shapes and their attributes (2.G.A.1, 2.G.A.2, 2.G.A.3)
Mathematical Practices
- Make sense of problems and persevere in solving them
- Reason abstractly and quantitatively
- Construct viable arguments and critique the reasoning of others
- 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
