Common Core is a set of new national education standards in the United States. Though the movement started at the state level, it is an attempt at creating a nationwide standardized curriculum for math and English literature for students in grades kindergarten through 12th grade. Common Core is important because almost all of the States have adopted its standards. This means that your child's curriculum for this upcoming school year will likely change. The standardized testing methods will also change, as the tests are considered to be more rigorous than the previous ones. Your child will likely learn new ways to approach literary texts and math problems. Some of these curricula changes will be significant for some schools, while they may be minimal for others.
