In my first year in the district, I had one class with Spanish, Turkish, and Portuguese students. Instead of having them just stare and pick up a few things here and there, I found that Microsoft Translator could do a decent job translating my real-time lessons into their prefferred language. Plus, some languages could even add the audio!
Imagine your class where students can hear you, their peers, videos, and more in their language. PLUS... the text translation is displayed on their screens accompanied by the English transcription as well!
This may be about 9 minutes of your time well spent. Don't worry, it will take a lot less time to use the platform.
