MAFS.912.G-GMD.2.4 - Identify the shapes of two-dimensional cross-sections of three-dimensional objects, and identify three-dimensional objects generated by rotations of two-dimensional objects.
1. The benchmark will be assessed using Drag and Drop Response, Graphic Response, Hot Spot Response, Multiple Choice Response, Multi-select Response or Simulation Response.
2. Items may require students to draw a line that shows the location of a cross-section..
3. Items may include vertical, horizontal, or other cross-sections as well as more than one three-dimensional shape.
4. Items may require students to explain/describe cross-sections or resulting figures from a rotation.
