It depends on what you want to do and where you’re going to school, actually.
For elementary education (i.e., grades K-5), the usual procedure is to get a bachelor’s in elementary education.
For secondary education (e.g., grades 7-12), it’s a bit more variable. In some states (and this is usually a state-by-state thing, but it isn’t quite as cleanly divisible as that) the normal procedure is for an aspiring K-12 teacher to get an undergraduate degree in teaching, and take other courses (essentially, the equivalent of a minor or maybe a minor+a couple more courses) in the subject(s) they plan to be certified in. In other states, the normal path is to get an undergraduate degree in the field of study you’ll be certified in (e.g., English, history, math), and then get a master’s in secondary teaching. (That second option is available most everywhere, as well.)
Either way, linguistics and liberal studies aren’t going to get you into K-12 education, unless you take linguistics with an eye toward getting a master’s in teaching English to speakers of other languages, but you’d still need a master’s in TESOL with teacher certification to do that. (Well, or you could take linguistics and get hired to teach English in certain countries outside of the US—but that isn’t at all what you’re after, it sounds like.)
