The document outlines two English lessons for upper intermediate students aged 16-18. Lesson 1 focuses on revising tenses through an online activity where students put sentences in the correct order. Lesson 2 revises tenses, prepositions, and jobs through four online pair activities: putting verbs in the correct tense, completing a crossword, choosing the right preposition, and choosing the right word. Both lessons are 50 minutes and aim to improve students' grammar through communicative writing exercises.
