Based on your query, I would recommend using Twee to create an engaging escape room activity for your ESL students.
Twee is a tool designed to assist English teachers in creating a variety of content, including questions, dialogues, stories, and exercises. For your specific need, you can utilize the Dialogue and Story Generator feature to create a narrative for your escape room. This could involve a series of dialogues and stories that revolve around the specific grammar topic you want to teach.
Additionally, Twee's Activity Ideas feature can be used to generate grammar exercises that can serve as challenges within your escape room. These exercises can be designed in such a way that students need to solve them correctly to "escape" from the room.
Lastly, the Vocabulary Builder feature can be used to generate vocabulary lists related to the topic. These lists can be incorporated into the escape room as clues or puzzles that students need to solve.
In summary, Twee provides a comprehensive set of features that can help you create an engaging and educational escape room activity for your ESL students.
