Common Core Connections: Math is the perfect tool for helping second grade students master Common Core math skills. The Common Core Standards for Math in second grade focus on four main areas: extending understanding of place value, building fluency with addition and subtraction, using standard units of measure, and shapes. This resource provides focused practice pages for targeting and reinforcing these skills and other second grade math skills while helping students connect comprehension with knowledge and application. Connecting the standards to content has never been easier with the Common Core Connections series for Math.
