In this Business English lesson plan for adults, students watch a video about some steps for writing effective emails. It includes discussion questions and conversation activities about email writing topics with colleagues and bosses, as well as deadlines. Students learn some important vocabulary terms related to these topics. For grammar, students do an activity on how to use 'would'. In the cooperation activity, students can collaborate on an activity for writing subject lines for emails and then writing short, informative, and direct emails.
