Before the start of your first E2K lesson, it would be good for the class to establish some group rules for group work together.
This is important as group work is an integral feature of E2K lesson. In addition, the pupils will be more inclined to follow the rule if they are the ones that set them.
If your school does not have an established ground rules for group work yet, the slides are a guide for you when you are facilitating the process of establishing ground rules with your pupils.
