I have a short class with a single second grade student (I'm a hagwon teacher), and I have been tasked with finding a book for him and assigning homework. His English is almost nonexistent; I have to speak Korean if I hope to be understood. However, he's a good student, and his mother is taking an active interest in his education. Are there any vocabulary-focused books you can recommend for him? Korean translations of vocab words are a plus but not required. Also I'd be happy to hear any advice on how to teach a 20 minute class with him.
Thanks.
