Identify and describe the results of translations, reflections, and rotations of 45, 90, 180, 270, and 360 degrees, including figures with line and rotational symmetry.

Remarks

Paper folding, mirrors, and computer technology may be helpful in developing student understanding of these concepts. Simple tessellation of plane may provide engaging opportunities for practice.

Test Item Specifications
  • Item Type(s): This benchmark may be assessed using: MC item(s)

  • Clarification :
    Students will identify a shape that is the result of a translation, reflection, and/or rotation of 45°, 90°, 180°, 270°, or 360°, including those with line and rotational symmetry.
  • Content Limits :

    For rotations, the center of rotation may be shown on the object being rotated. 

    The following vocabulary terms may be used: transformation, translation, reflection, rotation, clockwise, counterclockwise, line symmetry, rotational symmetry, and center.

    Items should include no more than two transformations.

Lesson Plan

Runway Rotations:

Students will use small paper airplanes to model rotations required to turn onto a runway. Students will rotate planes 45, 90, 180, 270, and 360 degrees. Students will identify and describe the results of rotations using benchmark angles.
