Read the NCTM Geometry Standard: Instructional programs from prekindergarten through grade 12 should enable all students to:
- Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships
- Specify locations and describe spatial relationships using coordinate geometry and other representational systems
- Apply transformations and use symmetry to analyze mathematical situations
- Use visualization, spatial reasoning, and geometric modeling to solve problems
Featured Topic: Coordinate Geometry
Help students learn about coordinate geometry through various grid activities such as coordinate grid pictures and coordinate grid games such as Capture the Penguins pictured at right.   Younger students learn to graph in the space while older students learn to graph ordered pairs on the intersection of the two lines.
