Oklahoma City, Oklahoma (CNN) Emboldened by support from across the country, Oklahoma teachers swarmed the state Capitol for a second week in their unrelenting quest for more school funding.

And by some accounts, Monday's crowd was the biggest yet.

Hundreds of schools closed Monday as teachers demanded $150 million more to replace dilapidated, decades-old textbooks and fund elective courses. They also want higher raises for support staff and themselves.

Some teachers walked 15 miles Monday to get to Oklahoma City.

They bring the support and advice of West Virginia teachers, whose nine-day strike last month led to a 5% pay raise

"When talking to West Virginia teachers, they told me the most important day of the walkout was the 2nd Monday," posted Alberto Morejon, the organizer of the "Oklahoma Teacher Walkout - The Time is Now!" Facebook group.

Millions of dollars granted, millions more wanted

The teachers' massive protest has already yielded some action by legislators.

Shortly before the April 2 walkout, Gov. Mary Fallin signed a bill that provided $50 million in funding for schools, increased teachers' salaries and gave pay raises to support staff. But the package wasn't nearly as much as educators demanded, so major school districts shuttered and the walkout ensued.

Now, two pieces of legislation could soon become law, getting a few steps closer to what teachers say they need:

1. The state Senate approved a bill amendment Friday that would require third-party retailers selling through outlets such as Amazon to collect sales tax from customers or inform them how much they owe in sales taxes. (The House approved the measure earlier in the week.) That bill could bring in about $20 million annually in education funding, but teachers say schools need a total of $200 million over three years

What Oklahoma teachers want vs. what they've gotten The Oklahoma teachers' union wants: $10,000 raises for teachers

raises for teachers $5,000 raises for support staff, such as janitors and cafeteria workers

raises for support staff, such as janitors and cafeteria workers $200 million in education funding What just got signed into law: Average teacher raises of $6,100

$1,250 raises for support staff

raises for support staff $50 million in education funding

2. The Senate on Friday approved a "ball and dice" tax for gambling. While Senate leaders said it will not add any income to this year's education funding, the Oklahoma Education Association said it would help in the long run.

But the OEA was livid about another Senate move: the repeal of a hotel and motel tax that it said would be paid by mostly nonresidents and would add millions in revenue.

The Senate followed the House's lead and repealed the tax as part of Bill 1010XX , thereby chopping $43 million from the education funding bill. Senators say they can make up that shortage through other revenue in the bill.

What will it take for this to end?

While thousands of students remain out of school indefinitely, OEA President Alicia Priest made clear what she thinks lawmakers must do to end the teacher walkout.

She said Fallin must veto the Legislature's repeal of the hotel-motel tax, and the Legislature must pass a bill ending the state's capital gains tax deduction

Until then, don't expect teachers to end the walkout.

"I think it will continue ... until they see the fully funded education bills that need to be passed," said Kingsgate Elementary Principal Karie Hill, one of many administrators who joined teachers at the Capitol.

The Oklahoma protesters join teachers from Kentucky, Arizona and other states who have been fighting for more pay, better education funding and improved working conditions.

In Kentucky, teachers also protested the passage of a pension bill, which they called a " bait-and-switch " move.

That bill, which would affect new teachers , is at Gov. Matt Bevin's desk. Supporters of the bill said the changes are necessary to save the state's pension systems.

While Kentucky teachers were protesting the pension overhaul last week, the state Legislature passed changes to the tax system called House Bill 366.

An analysis of that bill by the Institute on Taxation and Economic Policy found it would bring a huge tax cut for the richest 1% of residents, while the biggest tax increase would affect those making less than $21,000 a year. A fellow with the Kentucky Center for Economic Policy described it as "a tax cut for Kentucky's richest people paired with a tax increase for the middle class and the poor."

Bevin has until legislators return to session April 13 to sign the bill.
