Why We Often Use East Asian Math for Math Support

At Promontory, we are deliberate about the instructional methods we use to support our internally-designed, heavily integrated curriculum. Today, our focus is on mathematics. .

We do not adopt materials because they are fashionable. We study systems that consistently produce strong mathematical thinkers and ask what principles make them effective. Then we integrate those principles into our own framework.

One of the strongest influences on our mathematics instruction comes from high-performing East Asian education systems, primarily the models prevalent in Shanghai and Singpaore. These systems are generally not known for speed or memorization, but for disciplined reasoning and conceptual depth.

Several core strategies shape our approach.

First, we use a concrete–pictorial–abstract progression. Students begin by exploring mathematical ideas through hands-on experiences. They then represent those ideas visually through structured models and diagrams. Only after understanding the relationships involved do they move into symbolic equations.

This sequence matters. When students move too quickly to symbols, they often memorize procedures without understanding structure. When they build from experience to representation to abstraction, their understanding is far more durable.

Second, we emphasize visual modeling, especially for multi-step and proportional reasoning problems. Students learn to translate words into structured diagrams before solving them. This strengthens algebraic thinking long before formal algebra begins. It also trains the habit of asking, “What relationships are actually at work here?” before calculating.

Third, we prioritize depth over breadth. Rather than racing through a long list of topics, we spend time developing mastery. Students are expected to explain their reasoning, compare strategies, and justify conclusions. An answer without an explanation is incomplete.

These habits extend beyond mathematics.

When students engage in interdisciplinary work connected to global challenges, they must interpret data, evaluate quantitative claims, estimate outcomes, and weigh trade-offs. Strong number sense and structured reasoning are essential. Mathematical clarity becomes a tool for responsible judgment.

Our multi-age model also benefits from this approach. Because concepts are developed deeply, students can engage with the same core ideas at different levels of sophistication. One student may work with visual representations while another extends the same concept into symbolic abstraction.

Most importantly, these strategies cultivate intellectual discipline.

Students learn that mathematics is not about speed. It is about structure. They learn to slow down, analyze relationships, and defend their reasoning. They develop flexibility with numbers rather than dependence on memorized steps.

At Promontory, mathematics is one of the primary arenas in which thinking is trained. By integrating proven strategies from high-performing systems, we strengthen not only computational skill but clarity, precision, and confidence in reasoning.

Mathematics, when taught well, is not mechanical. It is a language of logic. And logic, carefully cultivated, supports sound judgment in every area of life.
