P4 Open Class - Figure Counting (Must-know topic for NMOS)

In the NMOS math competition, Figure Counting is one of the most consistent and frequently tested topics. Based on an analysis of past-year papers, this topic appears every single year, often in different formats that test a student’s observation skills and structured thinking. To give a clearer picture, here are some examples from past-year questions:

NMOS 2025 Q32

NMOS 2024 Q2

NMOS 2023 R1 Q14

NMOS 2023 R2 Q12

NMOS 2022 R1 Q12

From these examples, it is clear that while the diagrams may change, the core thinking skills required remain the same. Students who lack a systematic approach often:

Miss hidden figures
Double count overlapping shapes
Struggle to organise their counting process
