Mundo unido: Repaso y conversación focuses on a comprehensive review of grammar and promotes conversation and cultural awareness through the inclusion of many vignettes, media, and photos. Reviewers praised the clarity of the grammatical explanations and the diversity of the numerous realia-based exercises. The exercises promote an active use of the language with pair and group and self-expression activities. Closely coordinated with the accompanying reader, workbook, and cassette program, this grammar review may be used alone in an Intermediate Spanish, Grammar Review, or Composition/Conversation course or in conjunction with the other components if preferred.
