An English teacher is planning a lesson in which students will learn to request and give directions in familiar places. To organize the lesson coherently, the teacher lists four stages:

1.Students perform a role-play using a city map.
2.The teacher checks previous knowledge through questions about places and directions.
3.Students analyze expressions from a short model dialogue.
4.The teacher observes the role-play and records points requiring further practice.

Select the sequence that provides a coherent progression for the lesson.
