# 2nd Grade Math Practice - Common Core Standards

We have developed second grade mathematics practice tests that follow the common core state standards. We are not afiliated with the National Governors Association Center for Best Practices (NGA Center) or the Council of Chief State School Officers (CCSSO) which coordinate the CCSS initiative.

According to the CCSS, in second grade, students should focus on four critical areas:
a) extending understanding of base-ten notation,
b) building fluency with addition and subtraction,
c) using standard units of measure,
d) describing and analyzing shapes.

Second Grade Operations and Algebraic Thinking
2.OA: Students need to represent and solve problems involving addition and subtraction, to add and subtract within 20 and to work with equal groups of objects to gain foundations for multiplication.

Second Grade Number and Operations in Base Ten
2.NTB: Understand place value and use place value knowledge to add and subtract.

Second Grade Measurement and Data Practice
2.MD: The 2.MD CCS standards require second grade students to measure lengths in standard units, to relate addition and subtraction to length, to work with time and money and to represent and interpret data.

Second Grade Common Core Geometry Practice
2.G: Second grade students are expected to be able to recognize and draw shapes with specific attributes, to partition a rectangle into rows and columns and to partition circles and rectangles into two, three or four equal shares.
