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 :
Items may assess theorems and their converses for interior triangle
sum, base angles of isosceles triangles, mid-segment of a triangle,
concurrency of medians, concurrency of angle bisectors, concurrency
of perpendicular bisectors, triangle inequality, and the Hinge
Items may include narrative proofs, flow-chart proofs, two-column
proofs, or informal proofs.
In items that require the student to justify, the student should not be
required to recall from memory the formal name of a theorem.
- Calculator :
- Clarification :
Students will prove theorems about triangles.
Students will use theorems about triangles to solve problems
- Stimulus Attributes :
Items may be set in a real-world or mathematical context
- Response Attributes :
Items may require the student to give statements and/or
justifications to complete formal and informal proofs.
Items may require the student to justify a conclusion from a
