If you are a good teacher, you should know how to end the lesson well. As usually if a teacher want to end the class they will informing about the homework or something else. The good teacher will end the lesson by:
1. ending the lesson
The best way to end a lesson is to give students some kind of review activity, so that they may see the progress they've made in just one lesson. One of the most common and easiest to implement is simply taking the last 5 minutes of class to ask your students, “What have you learned today?” Notice, here, that you’re not the one telling them what they’ve learned. They may give you a list of new words, or say they learned to speak about what they did in the past or what they will do in the future, etc
Right before the last 5 minutes of class you can have some sort of performance activity, for instance a role play. Usually we don’t correct students during the role play so we don’t interrupt the flow, but when they’re done you can end the class with corrections of words or expressions they used incorrectly; things they forgot to say, etc…and your students will go home with these corrections fresh on their minds. Students may also give their opinion or feedback on their classmates’ performance.
Another great way to end your class is by asking your students to share whatever it is that you worked on that day: a fall collage; a painting; they may read something they’ve written. The important thing here is to give them a space to share something they've produced with the language elements they've learned. Even adult learners may read a letter or email they’ve written.
2. Informing homework
That is how to end the class or how to end the lesson in the class.
