Salient quantities are identified but the relationships between
quantities are not discussed (e.g., What are the slope and y-intercept?, “We know Jose’s speed, we need to find the distance he traveled.”)

Salient quantities are identified
and local relationships between quantities are discussed (e.g. at a
particular point: "what is the cost of plan A for 10 hours? Of Plan
B?")

General co-variation of quantities is discussed (e.g." as time increases, distance stays the same"; "when x increases by 1, y
increases by 2") or the relevant family of functions is identified.

Representations are interpreted
locally or in part (e.g., relevant quantities identified but relationship between quantities is not exploited (e.g., “from the
graph, when x is 4, y is what?”).
There are no connections between multiple representations.

Important global features of representations are explicated to
highlight the co-variation between quantities (e.g., relating the 'steepness' of a graph to a rate of change, using the representation to
identify the family of functions relating the quantities) or connections
among multiple representations are
explored (e.g. focus on parameters in an equation and how they affect the features of the representations,
concordances of different
representations may be highlighted).
