Many ELLs prefer to translate their work into their first language in order to better understand it. Below are several excellent resources to help you do this.
YouTube & ClosedCaptioning in Different Languages
Open up the youtube video and then:
Click settings (bottom right corner -- looks like a gear or bumpy wheel)
Click Subtitles
Click English (auto generated)>
Click Auto-translate
Scroll down to choose language
Multilingual Math Glossary
Students can choose a term, and then their language on a drop-down menu for a translation
Note: Terms are more relevant to earlier math levels
