You might be wondering how Texas got these books in the first place, so here's a quick history lesson:
In 2010 the Texas State Board of Education adopted new, more conservative learning standards.
Among the changes — how to teach the cause of the Civil War.
One side of the debate: Republican board member Patricia Hardy said, "States' rights were the real issues behind the Civil War. Slavery was an after issue."
On the other side: Lawrence Allen, a Democrat on the board: "Slavery and states' rights."
Ultimately the state voted to soften slavery's role, among other controversial decisions, and these standards became the outline for publishers to sell books to the Texas market — the second-largest in the country.
The final materials were approved last fall after the state board did some examination and said the books get the job done.
Brian Belardi from McGraw-Hill Education, the publisher of some of the new material, agrees. "The history of the Civil War is complex and our textbook accurately presents the causes and events," he said, adding that the Texas books will not be used for the company's clients in other states.
History professor Edward Countryman isn't so sure the materials do a good job.
"What bothered me is the huge disconnect between all that we've learned and what tends to go into the standard story as textbooks tell it," says Countryman, who teaches at Southern Methodist University near Dallas and reviewed some of the new books.
He thinks the books should include more about slavery and race throughout U.S. history.
"It's kind of like teaching physics and stopping at Newton without bringing in Einstein, and that sort of thing," he says.
"The history of the United States is full of the good, the bad and the ugly, and often at the same time," says Donna Bahorich, the current chairwoman of the Texas Board of Education.
While she admits the state standards didn't specifically mention important things like Jim Crow laws, she says she's confident students will still get the full picture of history if teachers, and the new books, fill in the blanks.
