 For neither correct:
(one root)

For example,
 Support Kyle:
a > 0, -5 ≤ b ≤ 5, c < 0
OR
a < 0, -5 ≤ b ≤ 5,

Level 3 students should
be able to use stated
assumptions,
definitions and
previously established
results and examples
to test and support
their reasoning or to
identify, explain and
repair the flaw in an
argument. Students
should be able to break
an argument into cases
to determine when the
argument does or does
not hold.
Level 4 students should
be able to use stated
assumptions definitions
and previously
established results to
support their reasoning
or repair and explain
the flaw in an
argument. They should
be able to construct a
chain of logic to justify
or refute a proposition
or conjecture and to
determine the
conditions under which
an argument does or
does not apply.

Level 0
students are
unable to
provide an
argument or
identify
obvious flawed
arguments in
familiar
contexts
Level 1 students
should be able to base
arguments on
concrete referents
such as objects
drawings, diagrams,
and actions and
identify obvious
flawed arguments in
familiar contexts.

Level 2 students should
be able to find and
identify the flaw in an
argument by using
examples or particular
cases. Students should
be able to break a
familiar argument given
in a highly scaffolded
situation into cases to
determine when the
argument does or does
not hold.

Student does not
meet criteria for
Level 1.
Student should give
justification to support
either Sandy’s statement,
Kyle’s statement or by
disproving both Sandy
and Kyle by supporting
the statement that the
equation can produce one
root (number 3).
Student justifies with a
sketch of a graph or a
