At this stage, it is the responsibility of
the teacher to ascertain that each student
understands the vocabulary and actions in the
song and that they can do the actions when
they are asked. It is for the teacher to decide
whether to do extra repetitions. Drawing on
my own experience, I feel it is always a good
idea to double-check student comprehension
of words and actions; students may say they
understood everything because they want to
proceed to the next stage right away. To check
student understanding, randomly name the
vocabulary that you have taught and ask the
students to do the accompanying actions.
