Dear, is there any textbook that is both interesting and can help learn listening, speaking, reading and writing? Yushan is not interested in the current textbook. He feels frustrated when he makes mistakes. He said he can understand half of it and not the other half. He hopes to learn the same interesting content as he did in the UK. Thank you. I want to add math content to his weekend class, one English class and one math class. Do you think there is a suitable textbook? He has learned multiplication and division in the UK.
