This grade 5 classifying test answer key gives the full solution and the scoring guide for each of the 9 test questions on classifying two-dimensional figures.
Use this answer key to score the classifying shapes test out of 20 points. Each solution has a scoring guide that shows how the points are awarded. Accept equivalent wording when the attribute is correct.
Grade 5 Classifying Test Answer Key: questions 1–5
Question 1: Triangles by sides (2 points)
(a) Two sides are equal: isosceles.
(b) No sides are equal: scalene.
Scoring: 1 point for each correct name.
Question 2: Triangles by angles (2 points)
(a) One angle is \(90^{\circ}\): right.
(b) One angle is greater than \(90^{\circ}\): obtuse.
Scoring: 1 point for each correct name.
Question 3: Name the figures (2 points)
(a) Both pairs of opposite sides are parallel and there are no right angles: parallelogram.
(b) Exactly one pair of parallel sides: trapezoid.
Scoring: 1 point for each correct name.
Question 4: Properties (2 points)
(a) 2 pairs.
(b) Any two of: four equal sides; both pairs of opposite sides parallel; opposite angles equal.
Scoring: 1 point for (a). 1 point for (b) for two correct attributes.
Question 5: True or false (2 points)
(a) True. A square has four equal sides and opposite sides parallel.
(b) False. A parallelogram does not need right angles. A rhombus with no right angles is a parallelogram but not a rectangle.
Scoring: 1 point for each correct answer with a reason.
Grade 5 Classifying Test Answer Key: questions 6–9
Question 6: Hierarchy (3 points)
(a) Trapezoid. (b) Rectangle. (c) Square.
Scoring: 1 point for each correct box.
Question 7: Every name that fits (3 points)
(a) Square.
(b) Any two of: rectangle, rhombus, parallelogram, trapezoid, quadrilateral.
(c) A rectangle is a parallelogram with four right angles. This shape has four right angles and its opposite sides are parallel.
Scoring: 1 point for each part.
Question 8: Sort the quadrilaterals (3 points)
(a) Shapes with two pairs of parallel sides: A, B, D, and E.
(b) B has four equal sides and no right angles.
(c) C has exactly one pair of parallel sides.
Scoring: 1 point for each part. In (a) all four letters are needed.
Question 9: Find the error (1 point)
A trapezoid with a top side of 7 cm, a bottom side of 13 cm, and slanted legs has only one pair of parallel sides. A parallelogram needs two pairs, so this trapezoid is not a parallelogram.
Scoring: 1 point for a correct example with exactly one pair of parallel sides.
