This document provides a summary of two books about teaching grammar: How to Teach Grammar by S. Thornbury, and Grammar for English Language Teachers by M. Parrott.
Thornbury's book reflects current theory by focusing more on helping students understand grammar rather than practice it. It provides sample lessons illustrating different teaching techniques and approaches. While generally clear, the book could benefit from a more critical presentation of some theoretical ideas. Parrott's book is concerned only with the "what" of grammar teaching, providing chapters on word classes, verbs, and complex sentences to help teachers develop their grammatical knowledge and reference grammar points in lessons.
