MAFS.912.G-CO.1.2 - Represent transformations in the plane, describe transformations as functions (given the original points, determine the resulting points). Compare transformations, i.e. translation (no change in size) vs. horizontal stretch (results in size change).
Also assesses: MAFS.912.G-CO.1.4 - Define transformations in terms of angles, circles, parallel and perpendicular lines and line segments.
1. The benchmark will be assessed using Multiple Choice, Multi-select, Graphic Response, Open Response, Selectable Text Response, Drag and Drop, or Simulation Response.
2. Items may require the student to be familiar with using an algebraic description, x → x + 3, for transformations or to use a function to describe a transformation (at least two transformations should be applied).
3. Items should NOT use matrices to describe transformations or require students to use the distance formula.
4. Items may require the student to find the distance between two points or the slope of a line.
5. Items may ask students to evaluate the accuracy or a verbal description of a definition.
6. Students may be asked to identify a line of reflection or degree of rotation that carries a figure onto itself.
7. Students may be required to draw a figure using a description of a translation.
