Competition may develop to unhealthy levels
When students begin to pass levels in Rocket Math, and color in the Rocket Chart in their folders, they naturally are proud of their accomplishments. Students want to tell me what level they are “on” when I visit classrooms. Unhealthy competition may develop among students sometimes. Some students begin to feel really bad about their slower progress, and students in the lead act arrogantly or disrespectfully. The Rocket Math Wall Chart is designed to curb that competition.
The Wall Chart puts all the students on the same team.
Over 700 star stickers come with the Wall Chart. Each time a student passes a level the teacher awards them with a star sticker, which they take up to the Wall Chart and put into one of the squares in the chart. Students fill the chart from the bottom up. The teacher sets a goal in a few weeks, which date is marked on the goal arrow, and the goal arrow is placed a couple of rows up from where the students are now. (You can just see that in the picture above.)
Students develop pride in their whole class.
If the students fill in the squares up to the arrow–before the date specified on the arrow–they earn a group reward such as extra recess time, or music during math, or a congratulatory note home, or a popcorn party, etc. 
In this way, each time a student passes a level they are putting up a score for the whole team. It is good for everyone. The teacher is able to praise the class for their hard work and accomplishments, and the whole class is able to feel good about their collective effort.
The Wall Chart shows visitors (like principals) how well the class is doing.
Passers-by as well as interested administrators can praise the class as a whole for their successes with Rocket Math. In many schools, classes post their completed Rocket Chart on their door with all 725 stickers in place! The Rocket Math Wall Chart becomes a focus of pride and recognition for the whole class. The price for the Rocket Math Wall Chart (#2005) of $20 includes directions, plenty of star stickers, four goal arrows, and the chart itself. They are cheaper by the dozen, $155 for all twelve.
