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

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
