What is one distinct part of a lesson, usually a single activity?

• A. Stage
• B. Phase
• C. Module
• D. Sequence

Answer: (A)

A stage is a distinct part of a lesson, usually a single activity. In lesson design, lessons are built from stages like warm-up, lead-in, presentation, controlled practice, and production. Each stage has a specific goal and a concrete activity designed to move learners toward that goal, making the lesson feel purposeful and manageable.

A phase, by contrast, tends to refer to a broader segment of the lesson that can include several stages and cover a larger objective. A module is a larger unit that comprises multiple lessons or topics. A sequence describes the order or flow of activities across stages or sections, not a single isolated part.

So, because the question asks for a single, clearly defined part of a lesson that can be embodied by one activity, the term that fits best is stage.
