Encourage students to explain their
solutions strategies, in particular
for shape E.
A–E.
Shapes A and D show
one-half and should be
circles.
F.
Responses will vary. For
shape E, if students reason
that they determined the shape
is half a circle then circling it
is a valid response. If students
reasoned that the entire shape
is shaded so they did not circle
it, that is also a valid response.
