**Prekindergarten through Grade 12**

The Standards for school mathematics describe the
mathematical understanding, knowledge, and skills that students should acquire
from prekindergarten through grade 12. Each Standard consists of two to four
specific goals that apply across all the grades. For the five Content Standards,
each goal encompasses as many as seven specific expectations for the four grade
bands considered in Principles and Standards: prekindergarten through grade 2,
grades 3–5, grades 6–8, and grades 9–12. For each of the five Process Standards,
the goals are described through examples that demonstrate what the Standard
should look like in a grade band and what the teacher's role should be in
achieving the Standard. Although each of these Standards applies to all grades,
the relative emphasis on particular Standards will vary across the grade
bands.
