A cone and a cylinder are shown.
Give one way that a cone and a cylinder are
alike.
Give one way that a cone and a cylinder are
different.
A 500
To answer this question correctly, students must identify at least one way that a cone
and a cylinder are similar and one way they are different. A cone and a cylinder are
alike because both are 3-dimensional objects. They are also alike because both have
at least one circular base (a cone has one and a cylinder has two).
A cone and a cylinder are different because a cone has only one circular base and a
cylinder has two. They are also different because a cone narrows to a point at one
end. Also, a cone has two faces and a cylinder has three.
Sample Correct Responses:
•A cone and a cylinder are alike because both are 3-dimensional. They are
different because the cylinder has circles at both ends and the cone narrows to a
point at one end.
•They both have a circle for a base. The cone has two faces but the cylinder has
three faces.
The focus of the task is to provide evidence of an understanding of describing and
comparing three-dimensional objects using their attributes. The response indicates a
correct statement of at least one mathematically relevant similarity and one
mathematically relevant difference between a cone and a cylinder.

sides.

Joe tells Janice that he is thinking of a quadrilateral (a shape with
four sides) with at least one pair of parallel sides (line segments that
are always the same distance apart). The five quadrilaterals with at
least one pair of parallel lines are a square, trapezoid, rectangle,
parallelogram, and rhombus.
Then, Joe says that his shape has four right angles (90ｼ angles).
Only squares and rectangles must have four right angles.
Finally, there are several acceptable rules. For example, the rule that
the figure has 4 sides of equal length will make the shape a square.
Or, only two sides have the same length describes a rectangle.

Six triangles are shown.

are needed to see this picture.
Circle each triangle that appears to be
scalene.
Explain how you decided which triangles are
scalene.
C 500
A scalene triangle is one where all three sides are a different length. In this problem,
there are three triangles that appear to have different side lengths:
･Circles the three triangles that appear to be scalene.
The scalene triangles are the ones that look like all of the sides are different lengths
and all of the angles are different measures.
Circles two of the triangles that appear to be scalene.
I circled those triangles because it looked like none of the sides are the same length.
The focus of the task is to provide evidence of identifying and defining triangles
based on angle measures and side measures. The response correctly identifies at
least two of the triangles that appear to be scalene and provides an adequate
explanation that demonstrates an understanding of the meaning of scalene.

Two triangles are drawn on the grid.
Which transformation - reflection (flip), translation
(slide) or rotation (turn) - can Bill use to determine
whether the two triangles are congruent?
QuickTime™ and a
TIFF (Uncompressed) decompressor
are needed to see this picture.
Explain how this transformation shows Bill that the
two triangles are congruent?
D 500
The triangles have the same orientation (they
face the same way). To figure out whether the
shapes are congruent (same shape and same
size), students can use a translation (slide) to
move one triangle so that it is on top of the
other triangle. If the sides of the triangles
match up exactly, then they must have the
same size and shape, so they are congruent.
