**Point Calculation**

Basic Mechanism: Points during the Math Challenge are tallied on the leaderboard. The calculation is based on

**the ratio of attending (active) students**to**total enrolled students**, multiplied by**the time these students spend on math each week**.Teacher Sign-In Bonus: Teachers can further double their class’s points simply by signing in to their account during the week of the challenge. This bonus is automatically applied to all their classes.

**Leaderboard and Ranking**

The leaderboard is a dynamic table displaying classes participating in the challenge, arranged by their current rank.

If classes have equal points, the ranking follows an Olympic-style format:

If two classes are tied for the first place, both get the "gold," and the next one is awarded the "bronze."

For a second-place tie, the first class receives the "gold," followed by two "silver" designations.

When three classes share the top spot, each class is presented with a "gold" distinction.

This method ensures fair and exciting competition, keeping classes motivated and engaged throughout the Math Challenge.

**Roster Changes During the Math Challenge**

The leaderboard dynamically reflects any changes made to school rosters:

If students transfer to a different class, their progress remains recorded under their previous class. Any new progress after the move is credited to the new class.

Class Modifications:

Teacher Transfers: All existing progress is saved when a class is handed over to another teacher.

New Class Creation: If a teacher creates a class during the math challenge and its grade level corresponds with those in the Challenge, it will automatically join the competition.

Grade Level Changes: If the grade level of a class is changed, either through Clever/ClassLink or by contacting support@happynumbers.com, the class may either be included in or removed from the Math Challenge, depending on the new grade level.

Class Deletion: If a class gets deleted, whether through Clever/ClassLink or support@happynumbers.com, it will be entirely taken out of the Math Challenge.
