4th Grade Lines, Rays and Classifying Shapes Test Solutions and Scoring (PDF)

1. It starts at A, has one endpoint, and goes through B: ray AB
2. It has two endpoints: segment CD

Scoring: 1 point for each correct name. Accept “line segment CD” and “ray AB”.

Two examples are shown.

Scoring: part a, 1 point for two lines that never meet and stay the same distance apart. Part b, 1 point for two lines crossing at 90° with the right angle marked or clearly square.

1. Angle P is smaller than a square corner: acute
2. Angle Q is wider than a square corner but not a straight line: obtuse

Scoring: 1 point for each correct classification.

1. It has a 90° angle: right triangle
2. 130° is more than 90°: obtuse triangle

Scoring: 1 point for each correct classification.

1. 2 pairs (both pairs of opposite sides have arrows)
2. 0 right angles (no little squares)
3. Parallelogram

Scoring: 1 point for each correct part.

Rectangle: (a) 2, (b) 4. Trapezoid: (c) 1, (d) 0. Right triangle: (e) 0, (f) 1.

(a) 2 (b) 4 (c) 1 (d) 0 (e) 0 (f) 1

Scoring: 1 point for each row if both answers are correct.

1. Main St and Oak St
2. 1st Ave and Main St (or 1st Ave and Oak St)
3. 60° is less than 90°: acute

Scoring: 1 point for each correct part.

1. always: every rectangle has 4 right angles.
2. never: two right angles leave no room to close a triangle.
3. sometimes: a rectangle does, but a kite-shaped quadrilateral does not.

Scoring: 1 point for each correct word.
