The NCTM standards are grouped into 4 grade bands

Prek-2 (Ages 5-7)
Grades 3-5 (Ages 8-10)
Grades 6-8 (Ages 11-13)
Grades 9-12 (Ages 14-17)

As well as 5 topic strands:

Number and Operations
Algebra
Geometry
Measurement
Data Analysis and Probability
In the web version of the Standards we have created 5 interactive e-Examples for each grade band, one for each content strand. The geoboard is the prek-2 example for geometry.
