Second Grade Math Resources

In Grade 2, instructional time should focus on four critical areas: (1) extending understanding of base-ten notation; (2) building fluency with addition and subtraction; (3) using standard units of measure; and (4) describing and analyzing shapes.

Operations and Algebraic Thinking
  • Represent and solve problems involving addition and subtraction.
  • Add and subtract within 20.
  • Work with equal groups of objects to gain foundations for multiplication.

Number and Operations in Base Ten
  • Understand place value.
  • Use place value understanding and properties of operations to add and subtract.

Measurement and Data
  • Measure and estimate lengths in standard units.
  • Relate addition and subtraction to length.
  • Work with time and money.
  • Represent and interpret data.

  • Reason with shapes and their attributes.

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.
