In this lesson, students learn about the structure and components of an email, specifically how to read and compose one. Using a hypothetical scenario, they will write an email inviting their friend Oliver to attend the National Pet Show. Key elements discussed include the email address of the recipient, subject line, greeting, body, closing, and signature. Students are encouraged to engage with an adult to discuss what an email is, their experiences with sending emails, and the basic requirements needed to send one.
