## Mathematical Content Standards

This task asks students to select and apply mathematical content from across the grades, including the *content standards:*

**Note:** These references are provisional: we are still developing our critera for consistently linking individual tasks to the CCSS.

## MAP Assessment Task Types

The task types indicate the breadth and depth of CCSS *mathematical practices* assessed by the task.
*Novice* tasks involve only MP2 and MP6 and do so at a low level.
*Apprentice* tasks add MP3 and MP7 but, because of the guidance within the task, do so at a comparatively modest level.
*Expert* tasks aim to cover the full range of practices.

**Note:** these task types offer a guide as to how tasks relate to the *mathematical practices*. We are currently considering whether referencing the specific *practices* relating to each task would be useful or appropriate.
