Continuing the red state education revolt that began in West Virginia, Oklahoma teachers launched a statewide walkout and converged on the Capitol building in Oklahoma City on Monday morning to demand more funding for schools.

The walkout had been in the works for roughly a month. Lawmakers nearly averted the move when they cobbled together a teacher pay raise package last week. But that bill, which became law, was quickly revealed to have funding holes. Teachers in districts around the state agreed to stay out of school until better legislation passed.

It is not clear how many districts will remain closed beyond Monday, or for how long. Tulsa Public Schools, one of the largest districts in the state, announced Monday afternoon that it would remain closed on Tuesday, with other districts likely to do the same.
