Listen and do activities are useful inside the classroom, for beginners games like Simon says are helpful for them to construct their vocab, example:
Simon say touch your leg
Toch your face
Simon says touch your hand
Touch your finger
And so on ... with this simple game we can review o check vocabulary understanding.
For more advanced students instructions using Simon says need to be more challenging, for example:
Simon says touch your left food
Simon says touch your right elbow
Simon says touch your forehead with both hands
This is a more challenging listen and do task for advanced students, but is simple for the teacher to check vocabulary understanding development.
