A 500 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.
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. A 500
The shapes shown are part of a design. What do all these shapes appear to have in common? A. All have four right angles. B. All have at least one set of parallel sides. C. All have four equal angles D. All have at least one set of perpendicular lines B 100
B. All have at least one set of parallel sides. B 100
B 200 How are a rhombus and a square alike? A. They both have four equal sides. B. They both have four right angles. C. They both have four equal angles. D. They both have only one pair of parallel sides.
Joe and Janice are playing a guessing game. Joe tells Janice that he is thinking of a quadrilateral with at least one pair of parallel sides. Then, Joe tells Janice that the figure has 4 right angles. B 500
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. B 500
The grid shows two shapes. What transformation changed shape 1 to shape 2? A. Rotation (turn) B. Translation (slide) C. Reflection (flip) D. No transformation C 100
Kevin has the two butterfly stickers shown. Which transformation could he use to see whether the butterflies are congruent? A. translation (slide) B. rotation (turn) and translation (slide) C. reflection (flip) D. rotation (turn) C 200
C 500 Six triangles are shown. Circle each triangle that appears to be scalene. Explain how you decided which triangles are scalene.
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. C 500
Jane will cut the paper shape shown below in a straight line from point X to point Y. D 100 What two shapes will Jane have after she cuts the paper? A. a square and a triangle B. a square and a trapezoid C. a rectangle and a triangle D. a rectangle and a parallelogram
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? 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. D 500
How many vertices does a pentagon have? A.3 vertices B. 4 vertices C. 5 vertices D. 6 vertices E 100
Which two three-dimensional figures have the same number of faces, edges and vertices? A. cube and rectangular prism B. triangular prism and rectangular prism C. triangular pyramid and rectangular pyramid D. cube and triangular prism E 500
