Meanwhile, the whole premise here touches on an even bigger issue. Why should 1 hour of Spanish be forced to be taught? English is effectively (if not officially) the main language in the U.S. Elementary schools should not be forcing students to learn anything besides English, nor should their teachers be forced to teach anything besides English.
I can see why they do it, even if english is the main language in the US, Spanish is widely spoken. At a young age children learn languages much much faster and it's not a bad thing to lay a basis then. It'll be a lot easier to pick up spanish in highschool if they had some already at a younger age. In my country children are taught english as a second language from around age 10. Then from age 12 they're also taught German and French though they do get the option to drop one of those at a later point usually.
I agree that learning another language can be useful. However, I think it should be optional, especially the choice of which language to learn. Due to where various immigrants settled and formed close-knit communities, there are regions in the US where you can find significant numbers of people that speak German, Czech, Polish, etc. It's great they are able to preserve their heritage, of which language can be an integral piece. As a result many youth growing up in those regions already learn 2 languages: English and one spoken at times by their family or community. There have been rumblings about schools forcing everyone to learn Spanish as a 2nd language, but for people in these various areas it would essentially be a 3rd language, one which may be of very little use. Consider the following map:

For the areas in blue, teaching Spanish probably may make sense. But for the areas in orange or yellow, learning Spanish might not be as useful as learning some other language instead.
Now take a look at another map:

This picture is from an earlier census, but it shows the concentrations of German-speaking citizens which hasn't changed much over the past decade I have relatives in Minnesota and North Dakota that are fluent in German and still speak it at times because there are enough people in their community that do. I learned German in high school, but I knew a bit of it from my relatives before taking classes. For the blue areas on these maps, it seems like they should consider teaching German as a 2nd language. There would be similar maps for other languages spoken in the U.S.
