The short version
Put both pages under a single menu item called “Learning Journey”.
• Sub-item 1 → “Our Approach” (methodology)
• Sub-item 2 → “Levels & Syllabus” (graphics + progression)

Why “Learning Journey” works best in Singapore
What locals already see Why it fits your two pages
Singapore schools, museums and even SMRT label excursions and staged programmes “Learning Journey” — the phrase signals step-by-step growth rather than a one-off lesson.

SMRT Corporation
Your Approach explains how you teach (the road-map), while Levels & Syllabus shows each milestone. Both are literally stops on the learner’s journey.
Dance studios here already speak of a “dance journey” in their copy (“one-stop … hub for your dance journey”).
New Heights Studio
Using the same wording in the nav gives instant information scent that this section is about how I’ll progress.
It’s short (14 chars), mobile-friendly, and avoids jargon (“methodology”) or school-sounding terms (“curriculum”). You keep the nav clean yet still professional; the fuller phrasing can appear in the page H1s.

What about other candidates?
Label Pros Cons (for SG adult-dance sites)
Curriculum Familiar in kids’ ballet world and often paired with “syllabus”.
Jeté Studios
Feels academic; some adults read it as exam-based or kids-only.
Method & Levels Literal. Two nouns in a single tab; longer, may wrap on narrow phones.
Learning Path Common in corporate training. Slightly less recognisable to the public than “Learning Journey”, which MOE popularised.
How We Teach Conversational, clear. Five words / 12 chars without spaces; more room than Learning Journey and harder to localise.
