The student cannot
determine a set of
values for A, B and C
or write an equation to
describe either balance.
The student cannot
explain why C must be
an even amount without
referring to his/her
solutions.
The student is not clear
on how to use the first
balance to show why B
might or might not be
greater than either A
or C.
The student determines
a set of values for A,
B and C and makes
a reasonable attempt
to write an equation
describing one of the
balances.
The student struggles
to explain his/her
strategy for determining
solutions.
The student cannot
explain why C must be
an even amount without
referring to his/her
solutions.
The student is not clear
on how to use the first
balance to show why B
might or might not be
greater than either A
or C.
The student determines
two or three sets of
values for A, B and C
and correctly writes
equations describing
the balances.
The student can explain
his/her strategy for
determining solutions.
The student can explain
why C must be an
even amount without
referring to his/her
solutions.
The student is not clear
on how to use the first
balance to show why B
might or might not be
greater than either A
or C.
The student determines
four or five sets of
values for A, B and C
and correctly writes
equations describing
the balances.
The student can
clearly explain his/her
strategy for determining
solutions; the strategy
is not a random guess
and test.
The student can explain
why C and B must be
even amounts without
referring to his/her
solutions.
The student can explain
why B might or might
not be greater than
either A or C.
