Each math course in secondary school covers topics in algebra, geometry, trigonometry and functions.
New York State began using integrated math curricula in the 1980s,[4] but recently returned to a traditional curriculum.
A few other localities in the United States have also tried such integrated curricula,[5] including Georgia, which mandated them in 2008 but subsequently made them optional.
[6] More recently, a few other states have mandated that all districts change to integrated curricula, including North Carolina, Illinois, West Virginia and Utah.
[9] Under the Common Core Standards adopted by most states in 2012, high school mathematics may be taught using either a traditional American approach or an integrated curriculum.
