Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
TEST ITEM SPECIFICATIONS

Item Type(s):
This benchmark may be assessed using:
MC
item(s)
Also assesses: MAFS.912.SID.3.7
 Assessment Limits :
Items requiring the student to calculate the rate of change will give a
specified interval that is both continuous and differentiable.Items should not require the student to find an equation of a line.
Items assessing SID.3.7 should include data sets. Data sets must
contain at least six data pairs. The linear function given in the item
should be the regression equation.For items assessing SID.3.7, the rate of change and the yintercept
should have a value with at least a hundredths place value.Items assessing FIF.2.6 should not be linear.
 Calculator :
Neutral
 Clarification :
Students will calculate the average rate of change of a continuous
function that is represented algebraically, in a table of values, on a
graph, or as a set of data.Students will interpret the average rate of change of a continuous
function that is represented algebraically, in a table of values, on a
graph, or as a set of data with a realworld context.Students will interpret the yintercept of a linear model that
represents a set of data with a realworld context.  Stimulus Attributes :
Items may require the student to apply the basic modeling cycle.Items should be set in a realworld context.
Items must use function notation.
Items may require the student to choose and interpret variables.
 Response Attributes :
Items may require the student to choose an appropriate level of
accuracy.Items may require the student to choose and interpret the scale in a
graph.Items may require the student to choose and interpret units.
