Grade 2 Common Core Math Practice

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)


  • 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
