The student struggles
to locate points B,
C and D once A is
selected.
The student struggles
to figure out where
A, B and C can be if
D = 100.
The student does not
generalise to how far
apart A and D must be.
The student correctly
determines a couple of
possible combinations
for the four points.
The student struggles
to figure out where
A, B and C can be if
D = 100.
The student does not
generalise to how far
apart A and D must be.
The student correctly
determines at least
three possible
combinations for the
four points.
The student can figure
out where A, B and C
can be if D = 100 but
does not consider all
possibilities.
The student correctly
notes how far apart
A and D are in his/
her cases, but does
not generalise to how
far apart they are in
general.
The student correctly
determines at least five
possible combinations
for the four points.
The student generalises
that A and D are 11
times as far apart as
A and B and uses that
information to figure out
possible and impossible
location combinations,
including multiple
possibilities when
D = 100.
