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
This benchmark may be assessed using:
- Assessment Limits :
Functions represented algebraically are limited to linear, quadratic, or
Functions represented using tables or graphs are not limited to linear,
quadratic, or exponential.
Functions may be represented using tables or graphs.
Functions may have closed domains.
Functions may be discontinuous.
Items should have a single transformation.
- Calculator :
- Clarification :
Students will determine the value of k when given a graph of the
function and its transformation.
Students will identify differences and similarities between a function
and its transformation.
Students will identify a graph of a function given a graph or a table of
a transformation and the type of transformation that is represented.
Students will graph by applying a given transformation to a function.
Students will identify ordered pairs of a transformed graph.
Students will complete a table for a transformed function.
- Stimulus Attributes :
Items should be given in a mathematical context.
Items must use function notation.
Items may present a function using an equation, a table of values, ora graph.
- Response Attributes :
Items may require the student to explain or justify a transformation
that has been applied to a function.
