Eureka Math, A Story of Ratios: Grade 7, Module 2: Rational Numbers

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.
