This works with all levels of ESL, and would succeed in a regular English class.  Write the beginning of a story on the board.  All the students write down what you wrote, on their piece of paper.  Now, each student has to add to the story.   The teacher can decide if the students should add one sentence or two sentences only, or if they just write for a given amount of time.

At the end of that given time, stop the students and have them each pass their essay on to the next student.  The next student has to read the composition given to him/her and then continues the new story with a sentence/time limit as before.  This continues until their own paper returns to them.

This activity means that students are composing, reading material written by others, using their imagination, practicing writing clearly so others can read their writing, and of course, practicing their English.  Students always love the final results when they receive their original paper back with a story developed by everyone.

Essay endings!  Pictures, stories, visual prompts are often the springboards that we start with to write creatively.  This idea is receiving the ending of a story and having the students write the body of the tale.

Teachers  can create their own lists, or use real endings of books from the library.  Here are some examples of essay endings.
--Shivers ran down her spine. It was the last time she would come here again.
--It was now green.  Flowers bloomed pink and large, and life seemed to have returned to it once more.
--and so, when they all returned home, everything was as it had been before.   Had it all been a dream?

Abstract dialogs are well known in the drama arena but are also excellent for advanced ESL students, or in any language classroom. The idea behind abstract dialogs is that the setting or characters are not given,  but rather a number of sentences whose underlying meaning has to be interpreted by the "actors".  If another language is taught, such dialogs can be easily created in the thatlanguage.

But abstract dialogs are also great for social groups. Parties, scouts, or an evening of fun, these dialogs are the perfect means for interaction or getting to know new people.  Here is an example of an abstract dialog script:

 A:   And he never did.
 
B:   You're  wrong. He did.

A:   Where  did you hear that?  Who told  you?

B:   Yesterday at the hair salon. Michael told me.

A:   I still don't believe it.

B:  Just have a look at this. Maybe you will  change your mind.

A:   I  don't  believe  it!

Participants have to decide who the speakers are, what they are referring to, what happened before and after this scene.

If you want to write your own dialogs or have students write them, you need a list of topics you can choose from.  If you are working on a theme, write a dialog to suit it, but if you are looking for creative ideas for writing or acting, here are some of the list on this site:
Argument between two friends / mother and son / dog and cat /  two flies on the ceiling / two policemen / three birds wanting the same worm.

Do you want to keep your kids entertained?  Instead of games, craft, computer activities or playing with toys, ask the kids to write a short story about some topics you can list and they can choose from.  Kids love creating stories.  Story writing can be taken seriously, or be done just for fun to express feelings or tell a tale.  Ideas for these kinds of short essay/stories can be seen here on the site.  Use the prompts for ideas, or think up your own.  Take a title from a book they know and tell them to write their own version of the story, or show them a picture and have them create a story about it.
