Several thousand Colorado teachers are marching to the state Capitol in Denver after rallying in a park across the street.
Friday's demonstration is the second day of protests expected to draw a total of 10,000 teachers.
The tone Friday was more festive than the day before.
A jazz band warmed up the crowd by leading them in songs like "Marching on Freedom Land." Teachers danced along, while others kept some beach balls bouncing over the crowd at Civic Center Park.
The band then joined teachers in a march to the Capitol, as drivers honked their car horns and police stopped traffic to let them cross the street.
Teachers in Arizona are also gathering for a second day Friday at their state Capitol.
