Major Work & Progressions

Two interesting ways to "slice" the Common Core Content Standards are: Horizontally, looking at the focus in each grade level, and Vertically, looking at how subjects flow from grade to grade.

Horizontal Slice: Major Work

Major work at each grade level called for in the Common Core 

Grade
Focus Areas in Support of Rich Instruction and Expectations of Fluency and Conceptual Understanding ​
​K–2
​Addition and subtraction - concepts, skills, and problem solving, and place value
3–5
Multiplication and division of whole numbers and fractions - concepts, skills, and problem solving ​
6
Ratios and proportional reasoning; early expressions and equations ​
7
Ratios and proportional reasoning; arithmetic of rational numbers ​
8
Linear algebra and linear functions

Vertical Slice: Progressions

The Common Core State Standards in mathematics were built on progressions: narrative documents describing the progression of a topic across a number of grade levels, informed both by research on children's cognitive development and by the logical structure of mathematics. These documents were spliced together and then sliced into grade level standards. From that point on the work focused on refining and revising the grade level standards. 

For the latest versions of the progressions, see the University of Arizona site.
