The student creates
a shape with some
parallel sides, but
without the required
types of angles.
The student is not
sure how to create
more shapes to fit the
constraints.
The student realises the
shape could not be a
triangle.
The student is not sure
how many sides are
possible other than
those he/she created.
The student creates
one or two shapes with
some parallel sides that
include at least one
correctly marked obtuse
and small angle.
The student is not
sure how to create
more shapes to fit the
constraints.
The student realises the
shape could not be a
triangle.
The student is not sure
how many sides are
possible other than
those he/she created.
The student creates
at least 3 shapes, all
with different numbers
of sides, that include
at least 2 pairs of
parallel sides, at least 2
correctly marked obtuse
angles and at least 2
correctly marked very
small angles.
The student has some
ideas for creating even
more shapes to fit the
constraints but is a bit
unsure.
The student could
eliminate certain
kinds of shapes as
possibilities based
on their geometric
properties.

The student creates
at least 3 shapes, all
with different numbers
of sides, that include
at least 2 pairs of

correctly marked obtuse
angles and at least 2
correctly marked very

The student clearly
articulates a strategy
for creating even
more shapes to fit the
constraints.
The student could
eliminate certain
kinds of shapes as
possibilities based
on their geometric
properties.
When asked, the
student realises that
any number of sides
greater than 4 is
possible.
