Set a purpose for teaching the five parts of a friendly letter. Ask the students whether they have ever received or written one. Discuss why writing friendly letters is useful. For example, they help you keep in touch with friends, teachers and other people.
Put a friendly letter on a white board or overhead. Write the corresponding part of the letter next to each section with a dry eraser marker. Explain what is in each part of the letter as you label it. Students should know the heading contains an address and date, the greeting identifies the recipient, the body contains the content and information, the closing tells the reader the writer is ending the letter and the signature identifies the writer.
Review the proper punctuation and capitalization in each section of the letter. Remove the letter from the overhead, and let students help create a new one. Write the parts of a friendly letter on the overhead, and invite different students to write the information that each part contains.
Reinforce the students' ability to identify the parts of the letter. Turn off the overhead and give students a worksheet containing a friendly letter. They can use pencils to independently label different parts of the letter.
