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
- Assessment Limits :
Items may require the student to be familiar with using the algebraic
description for a translation, and
for a dilation when given the center of dilation.
Items may require the student to be familiar with the algebraic
description for a 90-degree rotation about the origin,
, for a 180-degree rotation about the origin,
, and for a 270-degree rotation about the origin,
. Items that use more than one transformation may
ask the student to write a series of algebraic descriptions.
