Creating and maintaining classroom interaction is something that every teacher wants and needs to have.
Grouping student is one of the simplest ways to change the dynamics of the classroom. The technique called the RABBIT HOLE is an excellent dynamic for forming trios.
Procedure: Ask everybody in the classroom to stand up and then make them walk around in the classroom always getting mixed with the rest of the students (It´s necessary to make sure nobody is following a student in particular since the main purpose of this is activity is to get students who don´t use to work together into the same trio) then, when the teacher shouts "RABBIT HOLE!" two students have to grab each other by the hands and then get a third student into the rabbit hole which is formed by themselves. Once the trios are formed the teacher can assign the task to be completed.
