Coherence Across Grades
A Story of Units is not a collection of topics. Rather, the modules and topics in the curriculum are woven through the progressions of the CCSS. A Story of Units carefully prioritizes and sequences the standards with a deliberate emphasis on mastery of major cluster standards outlined in the CCSS. This meticulous sequencing enables students, upon completion of each module, to transfer their mathematical knowledge and understanding to new, increasingly challenging concepts.
