Second Grade mathematics is about (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. Major emphasis in Second Grade is placed on:

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.
