Well, they've already begun this. So Emma writes down all the words they've already gone over (it's a fairly short list so far, thankfully) and then hands the supplies to Crystal-Pyay. She points to the first word. "Bag," she reads, and then looks expectantly at Crystal-Pyay, so she can mark down her own word. Emma doesn't need to learn the language, necessarily, but Crystal-Pyay probably wants some way to remember what is what.
