Who do you want to talk to in English? What do you want to say to them? Take some time to practice now. Write a letter sharing your important idea with an important person to you.
Your letter might be an important business letter, telling a client why they should buy your product.
Your letter might be an important personal letter, thanking a stranger for being kind one day, or reminding a friend from long ago that you still think of them.
Your letter is for you. To see in writing the important things you have to say, and to see it in your writing so you know that you can say it in English.
Note for the teacher:
For some people How To is their English goal. How to use English at work, How to use English to make travel arrangements.
For people who want to learn English for COMMUNICATION, this is it. There is something they really want to say to somebody, to be heard and to be understood. The letter is a first step. It helps them think about who they want to talk to and what they want to say. Teacher feedback on the letter will let them know that they have been heard, that they can say what they want to say, and that it has value and meaning.
