iRubric: Understanding Multiplication rubric

•no answer attempted

shows limited to no
understanding of the problem’s
mathematical concepts and
principles
•may misuse or fail to use
mathematical
notations•
•attempts an answer

shows nearly complete understanding of
the problem’s mathematical concepts and
principles•
computations are generally correct but may
contain minor errors
•shows some understanding of the
problem’s mathematical concepts and
principles•
•may contain major
computational errors

shows complete understanding of
the problem’s mathematical concepts and
principles•
•executes computations
completely and correctly shows nearly
complete understanding of the problem’s
mathematical concepts and principles•
computations are generally correct but
may contain minor errors

gives minimal written
explanation of the solution
process; may fail to explain
what was done and why it
was done
•explanation does not match
presented solution process
•may include minimal
discussion of the elements
in a diagram; explanation of
significant elements is
unclear
•no written explanation of
the solution process is
provided

gives some written explanation
of the solution process; either
explains what was done or
addresses why it was done
•explanation is vague, difficult
to interpret, or does not
completely match the solution
process•
•may include a diagram with
some of its elements explained

gives a nearly complete written
explanation of the solution process; clearly
explains what was done and begins to
address why it was done•

•gives a complete written explanation of
the solution process; clearly explains what
was done and why it was done•
•may include a diagram with a complete
explanation of all its elements
