Hi Ms. Halfpop,

Most of the content that you assign should be accessible to your students via the Spanish version of the site (es.khanacademy.org). If you assign content in English, they can log into the Spanish site and view the Spanish version of their assignment. Their progress and scores will then sync back to your account on the English version.

Please note that there are a few exceptions to this, which are explained in the following article: https://support.khanacademy.org/hc/en-us/articles/115000797392-What-are-some-limits-around-assigning-content-to-students-in-different-locales-or-languages-

I hope this helps! Please let me know if you have any additional questions!
