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 :
- Calculator :
- Clarification :
Students will find a point on a directed line segment between two
given points when given the partition as a ratio.
- Stimulus Attributes :
Items may be set in a real-world or mathematical context.
- Response Attributes :
Items may require the student to find a ratio when given the
endpoints of a directed line segment and a point on the line segment.
Items may require the student to find an endpoint when given a ratio,
one endpoint, and a point on the directed line segment.
