Without a real-life scenario, so much is missing. Context provides opportunities for discussion and problem-solving. It enables pupils to "visualise" and develops their thinking skills.
As a relatively new recruit from teaching to teacher-training, I am willing to reconsider my expectations if I am indeed out of step. Perhaps trainee teachers or lecturers can add to these reflections? In the meantime, I continue to expect context.
