If you have a 4-skills ESL textbook of some kind, take a close look at it. You'll often find that it follows much the same teaching plan template as described above. There will be some sort of lead-in activity to set the context. Then, there will be some work with meaning and forms. After that, you'll find controlled practice and then free practice. Finally, there may be review or a suggestion for homework. If you're new to teaching or don't have a ton of time to plan lessons, then following the textbook like this is quite a good strategy. Just keep in mind this overarching framework and be sure not to skip steps, especially the meaning and controlled practice part.
