Common Core Mathematics is the most comprehensive CCSS-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 demanded by 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. The New York Edition is nearly identical to the national version but available earlier for the 2013-2014 school year.

Eureka helps students to truly understand math, connect it to the real world, and prepare them to solve problems they haven't encountered before. The team of teachers and mathematicians who created Eureka Math believe that it is not enough for students to know the process for solving a problem; they need to know why that process works. Eureka presents math as a story, one that develops from grades PK through 12. In A Story of Units, our elementary curriculum, this sequencing has joined with the methods of instruction that have been proven to work, in this nation and abroad.
