Mathematical Standards

Geometry and Measurement

  • Calculate the volume of composite figures made up of spheres, cylinders, and conic sections.
  • Visualize and reason with three-dimensional figures, cross sections of three-dimensional figures, and two-dimensional representations of three-dimensional figures.
  • Model real-world objects using three-dimensional composite figures.

Additional Resources

The resources in this section are the same for all challenges.

Pitch Preparation Resources

The following resources are here to support you as you plan to recruit people outside of the classroom to serve as experts and pitch judges.
