# Standard #: MAFS.912.G-MG.1.1 (Archived Standard)

This document was generated on CPALMS - www.cpalms.org

Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder).

### General Information

Subject Area: Mathematics
Domain-Subdomain: Geometry: Modeling with Geometry
Cluster: Apply geometric concepts in modeling situations. (Geometry - Major Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Date of Last Rating: 02/14
