Common Core Mathematics, A Story of Units: Grade 2, Module 2: Addition and Subtraction of Length Units

Common Core Mathematics is the most comprehensive Common Core State Standards-based mathematics curriculum available today.

• The modules are sequenced and paced to support the teaching of mathematics as an unfolding story that follows the logic of mathematics itself.
• They embody the instructional “shifts” and the standards for mathematical practice that are fundamental to the CCSS.
• Each module contains a sequence of lessons that combine conceptual understanding, fluency, and application to meet the demands of each topic in the module.
• Formative assessments are included to support data-driven instruction.
• The modules are written by teams of master teachers and mathematicians.

With Common Core Mathematics, second graders learn 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.
