The student cannot
create the required
shape.
The student does not
realise that there must
be other solutions.
The student does not
necessarily realise that
there are many choices
for the proportions of
the three subshapes of
the final shape.
The student creates at
least one shape made
up of 2 trapezoids and
a triangle with the total
area of 50 cm
2
.
The student counts
grid squares rather
than using formulas
to determine the areas
of shapes.
