Lesson-planning theory distinguishes a logical sequence from a psychological sequence when organizing content. A logical sequence follows the subject matter's own internal order (for example, cause before effect, or a strict chronological order), while a psychological sequence follows the maxims of teaching that match how a learner actually absorbs new material: known to unknown, simple to complex, concrete to abstract, and particular to general.

In the given lesson, the teacher opens with local festivals, which are already familiar to the students, then introduces less familiar festivals from other regions, and only afterward asks students to identify common themes across them. This deliberate movement from familiar, nearby content to unfamiliar, distant content is the defining signature of the psychological-sequence maxim, so the lesson demonstrates the psychological sequence principle of lesson planning.

• Flexibility describes a lesson plan's capacity to be modified in response to the class's real-time reactions during the lesson — a quality about mid-lesson adjustment, not about the order in which content of varying familiarity is introduced.

• The introduction–main body–conclusion, supporting materials/evaluation option describes a lesson plan's structural completeness — its component parts — rather than the rule used to sequence content by familiarity.

• Integration describes connecting a lesson's content with students' prior knowledge, existing skills, or values — a linking-to-the-past function, not the known-before-unknown ordering rule that this scenario follows.

As an independent check, the near-to-far maxim (a corollary of psychological sequence) gives the same result: local festivals are experientially nearer to the students than festivals from other regions, so they are naturally introduced first — confirming the known-to-unknown ordering from a second angle.
