Children and their leaning styles
All children learn different and in different ways, but according to their age their learning process is almost a like.
Taking this into account I disagree in the first statement, In my opinion and teaching experience I consider singing in the english class I very important and most of the students of all ages love to do it, but as teachers we should introduce songs and rhythms our students like.
I agree with he second statement, this is a way teachers can establish routines in the English class at first. But once students have all the activities clear, it´s possible to switch them from time to time.
I also agree with the third statement, but we can also use fast finisher as monitors to help students having trouble with certain activities.
