This document discusses grammar teaching and learning for young foreign language learners. It begins with a conversation between a teacher and student that illustrates how grammar is necessary to precisely express meanings. The document then discusses several key points about grammar teaching: grammar has a place in children's language learning when taught skillfully; grammar learning evolves from chunks of language and meaningful conversations; and grammar can be taught without explicit technical labels. The document also examines the development of learners' internal grammar, the influence of their first language, and trends in grammar teaching approaches. Finally, it proposes techniques for supporting grammar learning, such as noticing activities, structured practice, and introducing metalanguage in a meaningful way.
