The student struggles
to independently create
two triangles with
the same perimeter
where one’s height is
much greater than
the other’s. He or she
might miscalculate the
perimeter and does not
describe his/her shapes
clearly.
The student is unsure
that there might have
been alternatives to the
two triangles created.
The student struggles
to create a triangle with
a wide base and the
same perimeter.
The student creates two
triangles with the same
perimeter where one’s
height is much greater
than the other’s and
correctly calculates the
perimeter, but does not
describe his/her shapes
clearly.
The student is unsure
that there might have
been alternatives to the
two triangles created.
The student struggles
to create a triangle with
a wide base and the
same perimeter.
The student creates
two triangles with the
same perimeter where
one’s height is much
greater than the other’s,
correctly calculates
the perimeter and
reasonably describes
the shape.
The student expresses
some understanding of
what other alternatives
there might have been
to the two triangles
created.
The student effectively
transforms or describes
the transformation of
one of the triangles into
one with a wide base
by recognising that it
would have to have a
small height.
