# Math Content Sequence Key Tab

The **Math Content Sequence Key** tab displays the math content ordered by Math
Content ID.

- The Math Content ID indicates the unique ID assigned to a partner’s math content.
- The Title column indicates the title of the partner’s math content.
- The Sequence ID column indicates the sequence(s) to which the math content is best aligned.
- The Sequence Level column indicates the position of the math content within a sequence.
- The Sequence Info column indicates when math content is best aligned to multiple sequences.

For example, in row 3, the Math Content ID 19, *Decomposing numbers less than
20*, best aligns to Quantile sequence 104 at level 1. A level 1 designation
indicates that the math content appears at the top of the sequence, and all other math
content within the sequence are considered a prerequisite to the math content. To see
the complete sequence for a piece of content, input the Content ID into the **Sequence
Viewer** tab.

In row 12, the Math Content ID 28, *Comparing Lengths*, best aligns to Quantile
sequence 502 at level 3. A level designation greater than 1 indicates that the other
math content within the sequence can be considered either a prerequisite or extension of
the related content.
