Communication
Not using or inappropriately using
congruency/similarity to solve the
problem.
No evidence of geometric reasoning.
There were so many errors in procedures
that the problem could not be solved.

Partially using congruency/similarity to
solve the problem.
Some evidence of geometric reasoning.
Could not completely carry out geometric
procedures.
Some parts may be correct, but a correct
answer is not achieved.

Using congruency/similarity to solve the
problem.
Uses effective geometric reasoning.
Use appropriate constructions techniques
or proofs to arrive at solution.
All parts are correct and correct answer is
achieved.


Efficiently using congruency/similarity to
solve the problem.
Employs refined and complex reasoning.
Applies geometric procedures accurately
to correctly solve the problem and verify
the results.
Verifies solution and/or evaluates the
reasonableness of the solution.
Makes geometric relevant observations
and/or connections.


No justification of the solution, the
procedure cannot be understood or it is
unrelated to the problem.
No use or inappropriate use of geometric
representations.
No use, or mostly inappropriate use, of
geometric terminology and notation.
Incomplete justification; it may not be
clearly presented.
Some use of appropriate geometric
representation.
Some use of geometric terminology and
notation appropriate of the problem.
Steps are justified.
Appropriate use of accurate geometric
representation.
Effective use of geometric terminology and
notation.
Clear, effective justification detailing how
the problem is solved. All of the steps are
included so that the reader does not need
to infer how and why decisions were
made.
Geometric representation is actively used
as a means of communicating ideas related
to the solution of the problem.
There is precise and appropriate use of
geometric terminology and notation.
